Hey guys I am new to this forum and am looking for advice. I run a turbocharged NSX that runs 10.8 in the quarter and have a slow 60 foot of 1.7. I am trying to get a better 60 foot either through nitrous to spool the turbo sooner or changing the car to e-85 to build more torque at lower rpms. Does anybody have any input on the nitrous and turbo setup for drag racing ie. 30-40-50-60 hp setup and at what psi to shut it off at. I know you will not know the exact answer but a baseline setup to begin tuning at? Any input is appreciated. Thanks in advance

 

an anti lag/2step launch control in the EMS should be able to spool the turbo with out nitrous, most of the time a bad 60ft has to do with traction, what kind of tires do you run, it the car auto or 5/6 speed, what suspension,what EMS,how much power,what turbo(s) setup build info on the car
all these things will help with responses

 

THANKS FOR RESPONDING. I RUN AN AEM AND THE TWO STEP IS SET AT 4800 RPM SO I LAUNCH AT 4800 RPM AT 10 PSI OF BOOST. I HAVE RUN ET STREETS OR DRAG RADIALS. (THE ET STREETS I ACTUALLY HAD A 1.65 60 FOOT BUT THE CAR WENT OUT OF CONTROL AT 85 MPH).IF I LAUNCH THE CAR MUCH HIGHER I BREAK AXLES. I WOULD LIKE TO LAUNCH THE CAR AT LOWER RPM SO I DONT BREAK PART AS THESE PARTS ON THIS CAR ARE VERY EXPENSIVE AND GETTING HARDER TO FIND. THE CAR ALSO HAS A TWIN DISC CARBON-CARBON CLUTCH SO THERE IS 0 SLIPPAGE WHEN LAUNCHING. THAT IS THE REASON THAT I THOUGHT WITH SOME NITROUS OR A E-85 SETUP IT WILL ALLOW A LOWER LAUNCH RPM AND BETTER 60 FOOT TIME.

 

Call the guys at DriveShaftShop and have some axles built.

 

Bingo!

 

I HAVE NOT CALLED THEM YET BUT MY CONCERN WITH THIS IS IF I BUILD STRONGER AXLES, WILL THE TRANSAXLE BE ABLE TO HOLD THE POWER OR WILL I BREAK THIS NEXT. I AM JUST TRYING TO RUN IN THE LOW 10'S AND I THINK THIS IS POSSIBLE WITH A 1.5-1.6 60 FOOT TIME. I NOTICE YOU HAVE SOME IMPRESSIVE TIMES AND NUMBERS, IS THIS A STREET CAR AS WELL. LET ME KNOW IF YOU THINK I AM GOING IN THE WRONG DIRECTION WITH THIS.(I THINK I ALREADY KNOW YOUR ANSWER)

 

In the end you're gonna have to apply more torque to achieve better 60fts. be it more boost/rpm, nitrous, e85. those are not gonna help you get better 60fts. without breaking axles again. It seems you've reached the weak spot. Get some axles first. If you don't, and add nitrous to get more torque earlier, Bam, youre gonna break axles.

 

I UNDERSTAND AND HAVE ALREADY CONTACTED THE DRIVE SHAFT SHOP FOR PRICING AND AVAILABILITY. SO WHAT IS NEXT? RAISE THE RPM AND HOLD ON?

 

yeap

 

sorry, I was typing my response after you posted your last response. If you are falling out of boost, you could try raising the rev limiter. Just make sure you're datalogging every run and can compile some data to see which direction to go. Good luck!

 

....

 

^^ yes lol

 

Are you pre-loading on the launch? As far as you have gone in the NSX, I am assuming so, but nothing has been said regarding it.

 

no I am not pre-loading on the launch, as I stated I have a twin disc carbon carbon clutch and there is no slipping the clutch, so I would not know how to pre-load without slipping the clutch.

 

At 4800 I just fall slightly out of boost but if I go any higher in rpm I break parts. I was considering boost through vss so I can run higher rpm at launch and not break parts. At the track I run 15 lbs of boost, so maybe I should start at 10 psi and move it up as I get into second(or about 40 mph)and data log these passes.

 

you should still be able to slip it unless the petal is not set up right

 

I will try next time I go racing but I have 10000 miles on the clutch and have never been able to slip it (this is a personality of a carbon-carbon clutch). The clutch is like a light switch it is either on or off. The hotter the clutch gets the harder it bites. Also at 3000 bucks per clutch I am not that interested in experimenting with it. Do you have experience with this? That being said I will try it at least once next time I go racing. Thanks for the advice and keep it coming.

 

the clutch will wear out faster but that is just one of the things you have to deal with when racing, iv known guys running carbon twins that dont even get 5k out of them before they have to be shimmed, when others get 10k+ how much torque the car makes and how often you race it will have a lot to do with it
you may want to try a tilton flow control valve if your having trouble slipping it manually
what clutch is in the car?

 

it is a RPS rated to 1000 hp but I only have 600 at the wheels

 

YES I AM FALLING OUT OF BOOST THIS IS WHY I ASKED THE QUESTION ABOUT E-85 OR NITROUS. DOES ANYONE HAVE EXPERIENCE WITH BOTH OR ONE OF THESE(PREFERABLY NITROUS AT THE DRAG STRIP) TO SPOOL UP THE TURBO FASTER?
