Congrats to Munro

[Munro]

The 2835R turbos are probably the limiting factor on the R33 at the moment.They were chosen because on a 3 litre engine with 9.1:1 comp they give strong top end power & also come on boost relatively quickly - making the car very responsive for street use.

Now the car has morphed into a race car(is awesome on the street - but who am I kidding - it's no daily driver) the smallish turbos limit the current setup to around 850-900 hp.

I would like to fit 3037S & remap the motec to suit which should see the output raised to 1000hp without ringing it's neck - but

no-one has put their hand up for the 2835Rs & without selling them I can not upgrade.Larger turbos would increase lag, but on a car that rarely sees less than 7000rpm that would not be an issue.I would like to see the car run a 9.4 as it is - but drag racing is a funny thing. 9.6 might be where it's at, & thats fine.

Slicks would definately be faster.Possibly by 4or 5 tenths, but create other problems.For a start, there are 2 classes for GTRs -

"street drag GTR" running radial tyres (Nittos) or "Pro GTR" running slicks.It is much more than a simple tyre swap.To run slicks you must run 15" rims, which means removing all the GTR

brakes & running smaller non turbo style discs & calipers.Also the suspension has to be totally changed to suit the softer tyres.

another problem is that in Australia(under ANDRA rules) a 4WD is

not allowed to run non radial tyres all round - so unless it's an outlaw meeting at a non-sanctioned event - it wont comply.

The HKS car was exempt at Drag Combat last year as an exhibition car - but they nearly did not let it run as it did not comply with heaps of ANDRA regulations.The shock load through the drivetrain from a 4WD slicks launch can also cause severe breakages.It also means 4 slicks,4 rims, brake changes etc - add that up.Rather than do a bit at a time & slowly get the car into the 9s, I decided to go all out & stretch as far as I could.With the std engine my best was 11.10. Now with new engine my best is 9.66. That's a huge leap in drag racing.With fine tuning & 60' practice we may shave a tenth or two, but the next step into the low 9s could cost anywhere from $20-30,000.00

It's also about the look of the car. As it is it looks like a fairly normal GTR at first glance(I was driving down GJ rd recently & a copper coming the other way didn't even turn to look at it!)

With 15" rims, lexan windows all round,no headlights, & covered with stickers I think it spoils the look of a GTR.People can relate to it if if still looks like a street car.Hope the weather is good for Sat night - looking forward to 9500rpm & playing with my Holinger.

Munro, thanks for a really interesting reply, never realised it would be so involved. Have fun Sat night.

Would be good if anyone could get some vid of you on a run and put it up for us not fortunate enough to be there with you.

Cheers
