Adam 32 i was using this as a guideline to power to weight ratio like steve & Rev 210 pointed out maybe the dyno's/ operators are wrong cause 270 rwhp in a skyline should run at least 110mph or better if it is making this power seeing as the 300TT is heavier yet makes similar power & has run this mph! And refering to this bullshit mate's Zed did run this time there were at least 5 or 6 members from www.drivelinechatter.com @ willowbank plus 5 or 6 of us from Roma that witnessed the runs of TTZ32 & from memory he provided the timeslips on the forum as proof! Just because your mates ZXTT with a millonbucks spent on it is slow doesn't mean that someone else who has spent approx$2000 can't equal him! Subzero even ran a high 12 from memory with a R33 with similar mods to TTZ32 so there is the proof that it is possible! Actually while on the subject TTZ32 is listed on HPI's drag ladder as well! By the way how fast or slow? is your 32?

I've spoken to a few people about the boost dropping from 12psi to 9psi when the valve timing kicks in and they are suggesting possible boost cut from the stock ecu. Any thoughts? Might have go a power fc sooner than I thought. I was thinking haltech, but I'm starting to get pretty happy with my power output and I think the haltech might be an overkill if I'm chasing say 350hp @ wheels.

rob77,

I don't think it would be boost cut, the dyno reads boost at 20samples/sec and so we would see the spike in the boost if that happened, I can't imagine that it would have suddenly jumped to the boost cut without it being obvious. You'll need to do the dump anyway, and I'm pretty sure this could solve your boost issue aswell.

See'ya:burnout:

Not a boost cut.

Don't use a Haltech on a GTS or you will end up with IGN

problems, I have other shops GTSs in with this often inc

now. Use an ECU with Sequential ING drivers like the power FC

or Wolf Plug ins. People are going to say this is not true

but come down and see their customers cars in my shop.

The wide body R33 of Nicks has been in for many coils

as the E6K cooks them.

We have fitted other ECUs under warranty because of this problem and only sell Haltechs on demand now.

The E11 may have this sorted but at a cost.

its about 270hp. We're not sure why the dyno read that figure, it was a crazy figure considering what was done to the car at the time. A supra also pulled an odd figure too and everyone else on the day seemed to pull normal figures.

Rob, what do you feel would be an estimate of the cars power if not 270rwhp?

Not sure... I havent been in any other cars that have simular horsepower. The 235hp @ sst's dyno seems about right... who knows? Dyno's are best used to see gains after mods I think... going from my last 1/4 mile effort 235hp seems more in tune, but I'm sure I can get well into the 13's now on the right track.

Robs right Dynos are a tool only and as his car went on my dyno

as a total stocky and then with the new Exhaust so it was a good test for all the new work done and recorded a good gain and proved the worth of his outlay,Dynos job done now of to the Plex!

Don't race Dynos.

The yellow R34 GTS at the plex a few weeks ago recorded 13.5s

with robs power( on my Dyno) on huge street tyres.

The Power weight calculator Per4manz turbos have claims 13.3

should have been possible but slicks would have it on the money.

George Kontorinis Toyota made 522rwhp (3200lbs) and the

calculator claimed 9.16 and the car ran 9.2 and Miss P iggys

rail ran 8.88@148mph with 290rwhp and 1300lbs the calc was

spot on, lots of other cars to have been run this way so i feel

confedent in my readings but still recommend track testing.

13.3 1/4 mile hey... hmmm. I feel confident I can run at least a mid 13, maybe 13.7... dunno about the 13.3 :) See how I go on the 15th :( Who else is going to the drags then, should be a good time to go as the track is meant to be fully prep'd, meaning for some quick times. Munro was going to try and bring his GTR from adelaide, but I havent heard how its going lately at last mention he couldnt make it as the plex wouldnt offer any discounts for us to see a 9 second car :D

I might have to use a dyno shortly to do a quick setup of the S-afc II before the drag wars thing. I am going over seas and get back only just in time for the event and thus far I have had no chance to properly sort the new timing and fuel settings after the Cam gear install.

And sorry to rob for hijacking & talking BS! But as i said in my earlier posts, i was just using a car that i know its weight as it has been on a weighbridge, i was at Cramers dyno in Toowoomba when it got dynoed & i was there the night it ran the 12sec 1/4 times!

mod: i sent u a pm on how to post a link

    • Rotisserie is fully assembled apart from centre connector which obviously isn't required until the car is on it. It packs away fairly neatly and doesn't take up too much room. (Now that I actually have some room after my clean up!) Overall very happy with the quality of it.  Assembly was a piece of piss.  The only thing I didn't like was that the pins that lock the rotation lock wheels in place were a bit of a dick in a bucket scenario. It allowed the arms to rotate a significant amount even when locked in place.  To fix that i measured up the hole and went and grabbed a couple of 18mm fully threaded bolts and a thread tap to suit. I ran the tap through top and bottom so it was threaded both ends.  Then just threaded the bolt through both sides.  It has made a massive difference which hopefully you can tell in the before and after video how much difference it made. 20250207_161431.mp4   20250207_161431.mp4 Hopefully back working on the car over the next few weeks.   20250207_162801.mp4
    • I think my main complaint with your idea is that there is a veneer of idealism spread across it. You want the simple numbers to make it easier, but all they will do is make it easier for someone to come to the wrong conclusion because the fine details will kick them in the nuts. As it is right now, the tiny bit of arithmetic is NOT the obstacle to understanding what will fit and what will not fit. The reality of trying it is what determines whether it will fit. If you had a "standard rule" that R34 GTT guards have that magic 100mm space from the hub face to whichever side you were worried about, and someone said "excellent, this wheel is only 98mm in that direction, I'll just go spend $4k on them and jam them on my sick ride".....they would just as likely find out that the "standard rule" is not true because the rear subframe is offset to one side by a fairly typical (but variable) 8mm on their car and they only have 92mm on one side and 108 on the other.
    • It still combines inches with mm, especially when you have .5 inches involved, and mm and inches that can go in either direction. This would give a clear idea on both sides of the rim, right away, with no arithmetic. Even better if somebody gives you the dimensions of the arch of multiple cars. i.e GTR may be 125mm, a A80 Supra may be 117mm, or something along those lines. Yes, you can 'know' that going from a 10in rim to a 10.5in rim with the same offset moves both sides about 6mm, but you still have to 'know' that and do the math. Often it's combined. People are going from 9.5 +27 to 10.5 +15. You may do the math to know it, but if it was going from (I had to go look it up to be sure) 241mm/2 - 27 - 93.5mm from the center line to (more math) 266/2 - 15 (118mm) from the center line. Versus 93mm vs 118mm. It's right there. If you know you have a GTT with 100mm guards you can see right away that one is close to flush and the other absolutely won't work. And when someone says "Oh the GTR is 120mm" suddenly you see that the 10.5 +15 is about perfect. (or you go and buy rims with approximately 118mm outward guard space) I think it's safe to say that given one of the most common questions in all modified cars is "How do offsets work" and "How do I know if wheels will fit on my car" that this would be much simpler... Of course, nothing will really change and nobody is going to remanufacture wheels and ditch inches and offset based on this conversation :p We'll all go "18x9+30 will line up pretty close to the guards for a R34 GTT (84mm)" but 'pretty close' is still not really defined (it is now!) and if you really care you still have go measure. Yes it depends on camber and height and dynamic movement, but so do all wheels no matter what you measure it for.
    • But offsets are simple numbers. 8" wheel? Call it 200mm, near enough. +35 offset? OK, so that means the hub face is that far out from the wheel centreline. Which is 2s of mental arithmetic to get to 65mm to outer edge and 135mm to inner. It's hardly any more effort for any other wheel width or offset. As I said, I just close my eyes and can see a picture of the wheel when given the width and offset. That wouldn't help me trust that a marginal fitment would actually go in and clear everything, any more than the supposedly simple numbers you're talking about. I dunno. Maybe I just automatically do numbers.
