At the Holden vs Ford show this weekend (just gone), Eddy Tassones VZ Commodore ute made 1899rwhp, which is a new world record. The car has a 383 stroker V8 (based on the old Holden 5.0L block) with twin turbos, custom cam and manifold using 40psi and C16 fuel. Apparently they backed off before the redline because the engine was leaning out due to the fact it was not tuned properly (they only put the engine together the day before the event), so it only revved to 6500rpm, and the dyno graph indicates it will keep going. Summernats, here we come.

Edit: here are some pics. hopefully the guy I stole them off doesn't mind.... :)

The dyno sheet below was taken after the second run, the third run was 1898.9rwhp.

thats just insane,do you know if he is definitely running the same engine that he had in the vk

Yes it is the same engine from the VH, but it has been changed a fair bit. New turbos, plenum/intake, probably new cam, intercooler etc, I think the only thing the same is the 383 bottom end. It is making about 500rwhp more than the VH, so it has changed a fair bit.

Interestingly enough, if you were to see the boost graph, it makes over 600rwhp at 2000rpm, so the turbos may look laggy, but there is plenty of power down low. Don't forget they only revved it to 6500.

I window tinted Active Automotives Pink VN last week for that event... when they came and picked it up, they didn't say anything about that ute... what a monster.

The official record was held by Brett Waine in his twin turbo 372ci VC commodore, that was 1470.8rwhp on pump. Eddy's VH made 1376 on pump, and 1525 on C16. This figure was done on C16, but once the car is tuned, I would say it will get a tune for pump fuel for use at Summernats. Also, Brett Waines car is street registered, not sure about this thing.

looks like the same plenum,do you know what gear box he runs

Not sure what box, I will see if I can find out. The logical choice would be the T56 6 speed. He used to use a T5 in his VH for dyno runs and a powerglide for the track. I know that this thing has a manual, I will find out exactly what.

Well, the guy who owns the TRYHRD VX Clubsport (1200+rwhp), reckons that the Clubby is more drivable and better behaved than his Ferrari F355 that he uses as his daily driver.

If set up properly, there is no reason that it can't be driven. Mind you, Eddy Tassones cars are alot crankier than TRYHRD too. TRYHRD is so sedate, that if you didn't see the dyno readout, you wouldn't even believe how much power it makes. It is quiet and well behaved, it almost seems stock.

Good power indeed

What turbos are they?

gotta love the BOV's pointing to the sky :(

Every 15yr old kid's dream hehe

Just looking @ the numbers though

Ambient Temp: 19 deg

Intake Temp: 230 deg

If going from IT: 30 to IT: 60 can give a large power increase... imagine going from 19 to 230... the power correction figure would be astronimical.

I wonder if they had it on an engine dyno before putting it into the car.

They would be interesting numbers, not Dyno Dynamics "interesting" correction values.

230 degrees intake temp indeed.

I asked that very question myself. I have been assured by someone who was a competitor there (not sure if you have heard of the PSI-355 VR SS commodore with 900rwhp - the guy who owns that was competing there on the day) that on that particular run the inlet temp sensor failed causing it to revert to it's default setting which is 230. He said that Dyno Dynamics have assured that it did not affect power figures in anyway, and the sensor was fixed for the next run which was 1898.9rwhp. The guy who owns PSI-355 said that he tried putting the inlet temp sensor in the exhaust to see what would happen, his 900rwhp car gained 20hp, so it appears that the inlet temp does not have as much of an affect with high hp as it does with low hp.

I am no expert, just relaying information from people who were there. This is the actual quote which the owner of PSI-355 put up on the Street Commodores chat forum when I made a comment about the intake temp:

UD_LOSE: ALL WRONG..........This was the first issue they sorted out last night

Halfway through the second run the intake temp sender failed and went into default as 230 is the default code!!!!!!!! it was confirned last night that this had no affect on the figres by Mr Dyno Dynamics, Peter Humphrys so b4 you start shootin ya mouths off get ya facts STRAIGHT

Eddy will back up his numbers as he always does time and time again he does'nt need to defend himself he is as has been NO1 for years and proved this in every state!!!!

I hope he does roll this into summernats would be entertaining 2 say the least

good day

Does that one have to be pluged into a power point to get the electricity necessary to run it? The alternator doesn't have sufficient output to run the fuel pumps, igntion etc so it needs to be plugged into 240 volts to run.

:( cheers :D

PS; How can it be a World Record when I saw a supercharged big block door slammer make 2500+ hp on hub dyno is Las Vegas about 10 years ago?

eddy must have found himself a new tuner

last time in the vh the engine was still on the original anthony roderigeous tune from two years ago ( of course with some tweaking but nothing major changed for two hole years) and still goin strong

the last time i saw eddy run his vh was probably the last time it made good horse power! - it was spewing water out every where and did its final two runs with the radiator cap loose

im sure that alternator tucked down there would be decent sucker 100amp or something

fuel pumps would cause a draw but the car only gets run flat piss for 30 seconds MAX at a time so the load would beable to be kept up with for that short while

any ways

will be very interesting to see him again at summernats should be a good show down with craig munros vx

    • Can perhaps see how the R33 appreciators would think so.  
    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
