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

      Who has a Infiniti Q60, Q50 (V37)?

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
