Hey Ghost, do you have any timeslips from racing your car? What tune are you running? What mods...I want my car to spin in 3rd or 4th!

Hi, the title thread says 660whp but the the STD correction the dyno is 653whp, is it not? Ideally you shold post SAE corrected values. It is always best to under promise and over deliver. What did the car do unmodified on this particular dynojet?

Stock cars make 270-280 whp on this dynojet

You stated that MORE weight results in easier wheelspin. This pretty much underscores your complete misunderstanding of the physics behind this.

I believe you are spinning the tires in 4th and gave you the reasons why this may happen. With a properly setup car though I know for a fact you can easily hold 500ftlbs in 4th using PSS. I am not talking about spinning the tires from a clutch dump either by the way.

No, wheelspin happens when the amount of force applied (torque) is greater than the amount of resistance. More weight means more resistance against force applied meaning less wheelspin

Also, I'm not understanding why people are comparing an NA i4 to i6t??

Anyways, the s2k will have a pretty damn stupid powerband. Also, that s2k is peaking between 8000 - 9000 rpms.

Former_Boosted_IS's PTE6262 made 654whp @ ~6900 rpms but had a much better powerband

Just throwing that out there, peak numbers aren't everything

Don't feed the trolls. My old Turbo M3 somehow managed to hook up in 3rd gear despite having tire tech that is 10 years older than PSSes (Goodyear Eagle F1 GS D3s, tires 20mm narrower, suspension design that is 15 years older than ours, not to mention a little something called 580 rwtq. Could it spin in 3rd? Sure, if you drove it the wrong way. For the most part, however, it was the car's power gear. And 4th didn't spin either. Must've happened because it was 250 lbs lighter than my e92....smh.

Yay, physics! So THIS is how gigantic loaded up tractor trailers aren't just lighting their shit up all over the road????? no wai! :P

LOL, same!

I know more s2000's with 600+ hp on stock block that are running great than n54's

I would say that's a fair definition

I think its safe to say that the S2000 has been around a lot longer than the N54....Why are Honda's even being discussed?

Why THE F%^* do people ruin good car videos with cheesy pop-metal? Your Faux angst is not as cool sounding as an f20 @ 9000rpm

I'm talking about a roll-on at 4k rpms in 4th now that it is cold (Texas cold is only 40-50's F). Both of my e92s did the same thing. I would love to hook. I'm on stock e92/sport suspension.

My car only traps 118-119mph (93-94 in 1/8) which is consistent with its power (or lack thereof) and weight. In fact when I run on lower boost, which made considerably less tq, it runs nearly the same ET and mph (because you don't race at 3-4.5k, it's all about hp at the strip).

You people need to invest in some different rubber. I have continental DWS (all-season tires!) and they hook BETTER than my ultra-high-performance Dunlop Direzza Z1's cold or warm. RB turbos at 20 psi, 2nd gear, stock suspension, stock 18's, stock rear, no issues. Then again, I have a 6AT, but I can't see how someone would lose traction in 4th gear even on RBs let alone stock turbos. FWIW, I had a FBO + meth 135i 6MT with Procede before I switched over to the larger car.

My 335i on stock turbos 6AT trapped 118 with a 90.9 mph in the 1/8th mile. Guess it's gearing coming into play?

[ign335i]

What psi are you guys running your PSS at? I too am doing fine with these tires down to mid 30s. Below 32 they aren't good at all obviously. There is something entirely not right with your setup if you are spinning these tires at that speed in 4th. Camber, spring stiffness, tire pressure, wheel hop etc.

What's your peak torque?
I went out and was able to lose traction in 4th MT. One explanation to different outcomes is the road condition. In my case the icy roads were quite slippery.

that s2k must be the most irritating car to drive around town with almost no torque until 5-6K rpms ???

my tune only 335 makes more torque than that under 2K rpms!

Exactly. If you're spinning in 4th, something else is VERY wrong. I should also mention that many people may THINK they are spinning, when in fact they are feeling the wandering rear end feeling caused in large part by stock subframe bushings and toe arms. Two very different things.

I would lose traction in 6th...on ice. I would never be foolish enough to drive it in those conditions without the proper gear. Get some studded snows. Can't expect the car to perform if you don't equip it to do so.

Nah. You just jump on the gas and work the shifter. Torque is nice, but its overrated especially against an engine that likes to rev. Plus the shifter is easily one of the best ever, so its not a task to row through them. A stock S2k is much more fun to drive than a 335 (tuned or not), so i'm pretty sure a tuned one would be more fun.

I can spin 4th like crazy when I'm on jackstands. FBO+meth and E50, 6MT.

I can spin in 4th with my snow tires in fresh pow

Me too but they happen to pave the streets with coco butter where i live

[GeorgiaTech335coupe]

It got REALLY cold here today, down to about 57 degrees and I still wasn't able to spin my single turbo on DRs in 4th gear.
