Near 12mths since the last update apologies. Car is back running and driving. Have had a few runs at the drag strip also with a bit of success. Managed to run tje cars PB with a 10.88 @139mph with a 2.0 60ft. I have a stock 8hp converter and it's definitely too tight for my setup. But it drives on the street phenomenal. So happy to have converted from the sequential. Has made the car enjoyable to drive vs a what felt like a chore with the sequential. Looking a at few different options for converters waiting for some feedback from SDE if he can do one for me. Still a few minor things to work out regarding finalising torque reduction, I have it working but needs to refining.

I run 2x 4" Magnaflows. They're pretty good straight through aswell.

In other news, cooler and thermostat turned up. 1320motorspors come through with the goods on the cooler. And I've completed 85% of the ecu extension harness I've been working on in the background.

Thanks, I've seen quite a few mixed reports on HTG. He seems to be working through the issues raised and from what I can see he probably should have worked through the beta a bit more before releasing. I've just been shown these which I'll definitely be keeping any eye on considering it's Australian made and supported if my gearbox doesn't turn up before they're released. https://mectricmse.com/products/praetor-ptc

I've gone the HTG Gcu.

Yea that was my reasoning in going to the 8hp from the sequential. The sequential was fun to drive hard but when cruising was a bit clunky. Having had a self-built 6hp in my falcon(800hp) before the gtr was mint, cruise around none the wiser but plant it and hang on... bit of Jekyll and Hyde.

Hi All quick intro been kick around on and off this forum for close to 5yrs. Car in its previous iteration was as follows. Basic built 26, drop in cams, head studs etc, oil pump etc. Os88 sequential (now removed and moved on) Emtron kv8 controlled with a plethora of sensors. Now for the fun bit, I am currently working through a 8HP conversion with a kit from HPR. I'll throw some photos up of everything but I have created a IG just to make it easier to upload photos. https://instagram.com/32zila_qld?igshid=OTk0YzhjMDVlZA==

I'll start a new thread for 8hp or post my build thread to prevent from taking over the dct thread. I'll post link shortly.

From reading the supplied docs from HPR a small amount of massaging is required predominantly in vicinity of the transfer case. And a small bit where the 8hp breather is.

I'm going a little different route and going the 8hp but still with the adamat and hpr adaptors.

Hi, Me again. Long time between drinks Any chance anyone would have a 1.45 ar rear housing interested in swapping for a 1.05 to suit a 8474? Turbo is choking Uptop and keen to see with a gearbox change how a 1.45 would respond.

Hi All, Just wondering if someone somewhere would have the specs, ie floats etc that os build their boxes too. I've got mine out on the bench atm after doing the gear position sensor upgrade but can't bring myself to throw it back in until I check them including the dogs. The box feels fine but as you know it's a mission to get in and out and don't feel like having to get it out again in a few thousand ks. Ive found holinger GTR box manual but unable to locate a OS. I've spoken to one of the AUS distributors and they weren't able to help. Extremely helpful if I need parts but no manual. Cheers Welshy

Nah it was just the fuel pumps out of flow. But they are over 2yrs old now and not sure how much work they'd done before that as they come on the car when I bought it. I'd say you will be fine. I'll be keen to see your results as im soon to have a 26/30 in the shed as a incentive for the current motor to stay together.

Hahahaha yea that was me mate. I was surprised it went 500 as that was never the aim. Fuel system is -8 supply and -8 return and 1650cc boch motorsport injectors. As I mentioned I'm in the process of fitting 2x bosch 540 fuel pumps with radium check valves and a radium high flow fuel 10micron fuel filter.

Thats mine. It's being bled off boost for emap reasons. If I were you Shoot a 77 with a 3.0 bottom end I'd be going a 1.45 rear. Just my 2c. This also has leaking throttle body seals so the peak boost maybe a little high for the power for that reason. I can't justify pulling the manifold to fix the seals at this stage coz If I pull the stock manifold it'll stay off and I'll go a cpc/plaz with dbw to make the sequential better with flatshift. Put it this way power figure wise I'm out of fuel with 2x044s. Changing the setup to 2x540s in tank with a modified frenchys setup.

Nah mate Sean from what used to be EFI. He's now at Auto Care Centre in goldy

I guess it depends on where u class map:emap your stopping point. Ie in my instance that's where we stopped and class it as a restriction. Obviously a few things could help the power figure. Better head/cam setup and trial of the 1.45 rear along with not having leaking tbs also.

Apologies I may have mis wrote my post. Tuner stated that the cam and head setup was a restriction. Yea it tapers off quite a bit to match the emap. There's maybe a little more in the last 1000rpm but not a huge amount. Boost control is 4port via the emtron

Yes 1:1. How can't it be 1:1? 36psi on intake ~36psi in exhaust manifold. If emap was lower we cld push more boost till the emap rises all depends on where the tuner wants the ratio between map:emap.

Yea running a kulig kit. I'm not too phased on the dyno number to be honest burn. Last time I rolled off the dyno with 460hp I was surprising people with nearly the same in kw.

Dyno chart from the 502kw pull. On a side not don't send your car to the tuner with 12mth old e85. It doesn't help. ?‍♂️

Basic 2.6 build. Cp pistons, eagle rods, arp 2000 headstuds. Tomei 260 9.15mm cams. I don't think the head has been touched. BW EFR 8474 with 1.05 t4 rear, 6boost twin 40mm gate manifold, Custom 4" exhaust twin. CPC 90mm Intercooler. E85, BM 1650cc inj, 2x Bosch 044s. Seeing 30psi at 5k. Map/Emap are very similar from 5k onwards. Inj are pretty much done at 85%. As for the dyno number I can't be sure as in whether it's harsh or happy, its a mainline 2wd setup strapped pretty tightly.

I don't think the boost leak is huge. Emap is showing us that the rear housing /head cams aren't flowing enough to push anymore. Turbo is showing good potential at only 115k rpm we still have a bit of head room there. I'll post up a few screen shots of logs soon.

Finally... I've got some good news. My gtr is tuned. Bit of a push but we managed to make 502kw at the rear wheels on 36psi with tb seals leaking. My head and cams are seeming to be the restriction. Going from the data. I haven't had a chance to drive it yet as I have a 4wd code that's come up since removing the abs.
