13.4 second 1/4 for your 'stockish' R33. (A how to guide).

i crossed the line at 8k, and engine came off power badly. thats the way i got 13.872.

but if i shift into 4th it should be much better. i didnt mean for it to go to 8k.

whenever i changed to 4th i would get a 14.2-14.5

maybe i should imporve my shifts. (4th gear grinds) i need lighter oil.

8,000rpm isn't as healthy as 7,000rpm. If you aren't making power at 8,000rpm why rev it there and cop the extra wear?

At sustained revs beyond 6500rpm the standard pulley ratios will cause the water pump to cavitate.

Looks like a waste of time to me, hardly bigger just get a FMIC, I know your against it REV but someone already beat you to a 12sec pass with a stock turbo using a FMIC so they can't be all that bad with the stock turbo.

I ran a best ET of 14.4 yesterday @ heathcote.. Only had about 4 runs to try a few things unfortunately as it was pretty busy. Track was rain effected, so not sure whether that brought times down.. None of the other 5 SAU cars there could get under 15 for a stock(ish) car. Its not easy - not many VIC GTS-T guys are getting into the 13's with the stock ECU/turbo combos at all???

Tried 225/50's on stock 16" rims.. Didn't make much difference as far as i could tell as to traction..next time i will just use my street 235/45 on 17"s...

i noticed u were getting really bad launches and all of your runs 2.

wheel spin sux.. got aftermarket suspension, pineapples, and reasonable street tyres (ok, not the best, but should be enough) - not sure what else i can do to be honest.. I was getting 60' of 2.5's or so which isn't great.. even if i can knock that down to a low 2s if i got a good launch (damn helmet - can't hear shit), thats still only a 0.4s gain and only going to get me into high 13's..

After 2nd well just floored it and banged it into each gear right on 6,500 as quick as possible and foot right back to the floor .. to me they seemed like perfect changes - not sure whether i can do anything to improve that part?

I tried a bit of changing into 2nd at lower revs (5000rpm).. didn't seem to help - u just lose the speed which counters the increased traction.

Hey, I got a 14.7 before the rain kicked in [again] :)

I basically lost 1st gear to wheelspin on my 14.7 run which had a 60ft of 2.63 - this was my only run with traction control ON!

Surely the GTR-700 can do a better time than low 9's with a TS of 164.9mph? ~ I am suggesting all times were slow due to the rain-drenched track. They should have cancelled the meet but I dont think they wanted to lose the money :rolleyes:.

my quote from another thread:

my best of 14.7 is not exactly the car's potential IMO, but a bit more respectable than my first 2 efforts: 19 and 16.97 ha ha!

I think starting with a wet track was never going to be an easy task - my drag strip driving methods will be improving [i already know how to drive the car on the street].

I am a bit pissed off about the rain / times really but the day was good and the support / enthusiasm from everyone was great! thanks.

we have some good video footage too - online soon!

    • Please ignore I found the right way of installing it thanks
    • There are advantages, and disadvantages to remapping the factory.   The factory runs billions of different maps, to account for sooooo many variables, especially when you bring in things like constantly variable cams etc. By remapping all those maps appropriately, you can get the car to drive so damn nicely, and very much so like it does from the factory. This means it can utilise a LOT of weird things in the maps, to alter how it drives in situations like cruise on a freeway, and how that will get your fuel economy right down.   I haven't seen an aftermarket ECU that truly has THAT MANY adjustable parameters. EG, the VAG ECUs are somewhere around 2,000 different tables for it to work out what to do at any one point in time. So for a vehicle being daily driven etc, I see this as a great advantage, but it does mean spending a bit more time, and with a tuner who really knows that ECU.   On the flip side, an aftermarket ECU, in something like a weekender, or a proper race car, torque based tuning IMO doesn't make that much sense. In those scenarios you're not out there hunting down stuff like "the best way to minimise fuel usage at minor power so that we can go from 8L/100km to 7.3L/100km. You're more worried about it being ready to make as much freaking power as possible when you step back on the loud pedal as you come out of turn 2, not waiting the extra 100ms for all the cams to adjust etc. So in this scenario, realistically you tune the motor to make power, based on the load. People will then play with things like throttle response, and drive by wire mapping to get it more "driveable".   Funnily enough, I was watching something Finnegans Garage, and he has a huge blown Hemi in a 9 second 1955 Chev that is road registered. To make it more driveable on the road recently, they started testing blocking up the intake with kids footballs, to effectively reduce air flow when they're on the road, and make the throttle less touchy and more driveable. Plus some other weird shit the yankee aftermarket ECUs do. Made me think of Kinks R34...
    • I do this, I also don't get the joke  
    • Return flow cooler will be killing you I reckon. You can certainly push more through a low mount setup but they're good numbers for a stock looking engine bay.  Mine made 345rwkw (hub) at 22psi on 98 with a "highflow" on a stock manifold but it's a long way from a normal high flow or standard engine. I used one of those Turbosmart IWG-75's and it was great with the Motec running closed loop boost with pressure being applied to both sides of the diaphragm. 
    • Hey man do you have pic of adaptor plate by any chance I need to match up the bolt holes as my gearbox adaptor plate ones are way off the only bolts of starter motor are matching thanks
