Do you think its possible to build an r33 gtr that will do 10sec 1/4mile @ 140mph on pump fuel?

Im trying to get some info for a friend whose looking at building a new car that will go 10sec or quicker yet run 140mph or close to it all on 98 pump gas.

So far he is looking at the 2.8l stroker, usual mods, head work cams, proper fuel set up. Turbo he is looking at the new turbonetics GTK1000.

I know its abit of a hows it going question but any information would be help full. Those who have run 10sec passes could you list your mods and times and mph.

Thanks

Bobbo here in WA ran 10.2 at 122mph with T76.

The low MPH is because he missed 5th gear and coasted across the line.

The car had 672rwhp and was running a T88-34D with a HKS 2.8L and HKS H-Pattern Dog Box (pump fuel, no NOS).

he hasnt got much aCCess to c16 or so. I know tens in a GTR is doable how ever, what about say hi 9s at 140mph? for some reason his goal is to hit 140mph down the 1/4 on pump fuel at what ever quickest time.

i run high 9's on Sunoco fuel @ 139.6MPH...but im holding the car in 3rd gear so i dont MPH quicker, 9100rpm in 3rd = 139 MPH

this not only affects MPH but obviously the ET as well.

reason for this is i have no parachute and dont wish to be logged by ANDRA stewards for breaking 140

Cars engine is so efficient it only produces 30 more KW on Sunoco than with BP98..so the statement that "race fuel unlocks HEAPS more power" is not correct, it depends how efficient or inefficient the engine is. A less efficient engine will see more of an increase with race fuel. Race fuel in more efficient engines is generally run for safety and a bit of tuning "headroom" (this is the only reason we run sunoco).

so with parachute fitted and pulling 4th gear with pump fuel id say its more than possible to run 9's @ 140 on pump.

How much more ignition timing do you run from BP to sunoco? when i tried BP to Elf turbo max i could easily run 15 degrees more. As you would know simply switching to race fuel does nothing, but gives you the opportunity gain the extra power.

wont quote our timing figures but only ever run up to 6 deg more on race fuel.

we still make massive power and run the numbers at the track for the set-up we have.

Also have only ever broken 1 engine (oil pump failure) and that was due to over revving and ignition cut rev limiter....not tuning

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?

      See if you can thermal epoxy a heatsink or two onto it?

      The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.

      And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R

      So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
