How To Launch A GT-R

[BrooklinsFinest]

Well ,my car is almost here and I'm already getting chalenged to good 'ol fashioned American drag races! It won't be happening on city streets of course.

The biggest challenge is gonna be up against a co-workers '05 Mustang GT. His car is no slouch tho, its got long tubes, cat delete (not a fan) Ford racing cams, and a dyno tune. The car was built by Matt at DaSilva racing, and it is pretty quick. He says it runs high 12's to low 13's.

I guess my question is, does my R33 with a tune, down pipe and cat back stand a chance of destroying this white trash Ferrari? And if so what RPM should I launch it at?

How do you guys launch your cars? I hear alot of people saying that they dump the clutch at 7 grand and let the Attesa do the work, but that seems pretty harsh for my new baby-

[GTRADDICT]

7k dump!!! LOL I hope you like changing clutches.
Does your r33 have a tunable ecu?

All in all, you might have a chance.

There's no magic way to launch (safely and not f***ing your driveline). Just practice on what works for you.

Have fun!!!

P.S. Even if you see it on youtube... Don't mean YOUR car is build for it...

plus even if it's a jdm it wont beat pure american muscle.

300hp vs 400+hp. hmmm

The mustang dynos at 320 (so he says) to the rear wheels- Hes on 9" toyos, with a 410 gear. He has been know to bend the truth slightly- I have a mystery switch in the car, I can only assume its for a dual tune. I'm pretty sure I'm gonna take him. He's gonna try so hard that he'll most likely spin the tires.

The best way I've found to launch is pretty hard on clutches. My GTR had a OS twin so it took it like a champ.

The higher the RPM is the better and slip-dump the clutch. It's sort of hard to explain, you have to slip the clutch very aggressively until you build boost, then dump it. If you just dump the clutch it will usually bog down, that's why you slip it first.

With this technique I did a 1.70 60' with narrow garbage china tires. I think they were only 225 or 235 wide, no lowered tire pressure or anything either.

My car with similar mods to yours ran a 12.9 on ~14psi/1 bar. It was an R32 though which I believe is a bit lighter.

First 60', no issues at all, you have a huge traction advantage. Beyond that it would be questionable, as horsepower to the ground will determine the outcome.

In Group A racing, it was a 7,000 RPM clutch dump and 4WD that gave the GT-R an incredible hole-shot advantage over the rest of the field. The other cars appeared to stand still at the drop of the flag! (that was the reason the Audi 4WD cars were banned in BTCC as well...)

Keep in mind that they did snap quite a few driveshafts with the Group A cars!

I think the mustang will slip and spin at the start

[BrooklinsFinest]

I saw his best time today.... 12.08 at 114 mph- pretty impressive, but there was a stack of mid 13's and a few low 14's too- lol. Ima eat him! worst case scenario, I lose then smoke him at mosport or tmsp

[Joker]

if he managed a 12.08 ur dead in 1/4 mile or more. The range of times means he dosen't know how to drive it or traction is an huge issue. These things (GTR's) brand new would only do a 12.8-12.9 on a perfect launch. 15 years later ur in the mid 13's low 14's. Save your clutch and don't bother. The mustang won't break in the race but the GTR may.

Drag slicks. Not drag radials like BFG's or Nitto's. I mean honest to god drag slicks.

Rev limiter for 3 or 4 seconds.

Drop clutch.

Blow front diff to pieces.

I got a r33 as well and managed to run a 12.7 with ignition breakup. exhaust downpipe intake cones. Was doing 7100ish launches(15+) with an unknown clutch never had an issue. I just threw 255 star specs on however and now when I try this they dont spin and just bog. Depending on your tires would make a huge difference on how you launch.

[BrooklinsFinest]

Im gonna be honest, he had one low 12 run, and like thirty mid to high 13's- I'm willing to bet that when he ran the 12 lightning struck, or he has one of Matt DaSilvas time slips- lol

[GTRADDICT]

I would brag at how much I get traction at the start and so on... Pump him up so he does a mistake lol. Good luck buddy!!

[BrooklinsFinest]

Im gonna make sure to bring an in car camera, and have someone with a camcorder in the staging area, and maybe a third in the stands- Its gonna be epic. My R33 is pretty stock (exhaust, coilovers, rims) and I'm most likely gonna keep it that way. It'll be nice to see what it does against a fairly well tuned american NA V8. My buddy said he gave it to a NSX last night, and the NSX driver was pissed!

+1 on Braden's comment.

My car did 12.2@118 last year. HKS intake filters, 2860r-5 turbos, and exedy single plate. And my reaction time is pathetic (>1 second.)

Just in case, don't even think about burning out to warm up your tires.

I sit at the line and bounce the RPM between 4-6k in time with the lights. On green you give 50% throttle while bringing the clutch out. Once you're engaged go 100% throttle. AWD takes care of the rest, skyline loves spinning all 4.
