Hi guys,

got the car wheel aligned today here in brisbane from bridgestone select, done an awsome job. We settled for Rear left +1.14degree Rear right +1.29 and both toeing in 2.7mm which under full squat the car will pull the rear wheels back to 0 degree and 0 toe, so should hook up good.

Front left -1.83degree and front right -1.46degree, front toeing in 0.8mm and got the caster sorted aswell, because the left front was hanging back the right front was pushed foward, so thats all good now too.

I am a little worried about the amount of toe on the rear as it does seem like alot.

After looking at that video, it doesn't look like your getting enough rear droop to zero out your ass end after the initial launch... Spring rates, compression and weight transfer looks pretty good though.

I'd hate to see the car start getting sketchy in the top end for the sake of marginally more traction (that you may not need).

Must be a blast to drive!

Justin.

The Japs were going faster in the late 90's with H-patterns?

They probably were...it's been a while :)

Definitely fastest/quickest H-pattern street GTR either way.

Looks like there is plenty left in, too.

Hi Guys, Just driving home back to Mackay, I will put the link on the 8.97sec pass up. Also Theo Willot Still holds the World record for fastest H pattern GTR I missed out by .02 of a second, and on Sunday I was gona to smash that time with an ET of 8.8. But third gear smashed into a million bits. I was 3MPH faster by half track than my 8.97 and thats also lifting of cause 3rd blew up. We are under the impression that the selector fork has bent therofore only half engaging 3rd and stripping the teeth off the cog.

Im laying down the challange that this car will run a Mid 8.5sec pass or lower with this H pattern box, as I am only running 150MPH to get 8.97secs and theo done 8.95 at 162MPH, I am only currently running 900-950HP with alot of go juice up my sleeve. Haha.

I will upload the other video my GF filmed later tonight when we get home,

cheers Matt

There is no evidence of a Japanese or American or euro or pommy GTR even running the 8s with a H pattern box, me and theo are the only ones to do it, Yes there are plenty of GTR in the 8s and 7s but they all run Sequential boxes or Airshifted liberties or Lenco gearboxes, which are an easy 0.3 of a sec quicker. Thats why Theos time is a World record that himself or me could ever find recorded.

Yes, how could I forget Theo's time....I don't think it was registered though :D

Either way, fantastic result and hope to see it get close to [RH9GTR]'s 8.47 auto time

btw, what does the car weigh in race trim?

Check out these videos... There are several running 8's with H-patterns

    • If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.
    • This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).
    • I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.
    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
