just depends how you drive it LOL You shouldnt brag about how little hp it took to break a tranny. Hell NA cars can break trannies if you drive them like sh*t enough. I think the best solution thus far is the B15/P11 The case is way better and the gears are thicker. I really think youd have to do somethign stupid or completely disregard that you have 500WHP to break one. Maybe drain all the fluid out first or run 31" slicks LOL
hell ive been turbod for about 1 1/2 years anywhere from 250 whp up to what i have now and i have yet to break a tranny that wasnt completely my fault, In other words ive yet to break one because i was making too much power.
I broke my case on my very first trans because i didnt get the bolts tight on the back motor mount and the case cracked when i was at the track.
The tranny i am still currently using got messed up due to a horrible mis shift into second where i still tried to slam it into gear basicly without the clutch even depressed. Syncro got screwed, But i fixed the second gear but still have no 1st gear other than that this tranny has seen countless punches under heavy heavy load and i have yet to break 3rd gear and thats where the fun was, haha now the fun is in 4th gear since 3rd completely goes up in smoke and goes nowhere.
But yeah dont slam gears and ease the throttle on gears that will hold and you will be fine, I dont ease 3rd since it just goes up in smoke, hahaha
But yeah the b15/p11 trannies have been proven to be much more durable to hard use and drag racing where you would have to quickly change gears and be on constant heavy load. So thats what im going with since i can pick one up for less than 300.00 in mexico.

1999 P11 trans with a B14 diff and 4.18:1 FD. Even P11 or B15 transmissions will break under that power. Just a matter of time.
^I think a P11 tranny treated all the way should last a bit longer than the 91-99 trannies.

No disagreement there.
Luckily for the trans, most of the cars that make this kind of power either aren't driven much or kill the owner in a short matter of time.
Mine, for example, hasn't been started in 2 years. Jose's took a year to get broken in (IIRC), Ron's got sold to some sissy in NorCal, Mike parks everything in the garage and leaves it there and I'm not sure about Sarah's car.
lol a cage is gonna be a must being i could baby the car down the strip and run an 11 second pass, hahaha my t28 setup was easily in the 11's but never got to make a pass to get kicked off. This setup makes the t28 look like a joke haha.
A cage is to come along with a recaro driver seat to replace the heavy stock one, haha. But as far as right now the car doesnt have a cage. lol
Oh and the car is daily driven too btw. Again ive yet to shatter a 3rd gear, i had that one tranny that sheered every single gear on the stack but that was due to a bad main gearstack bearing causing the gears to separate but that happened just normal driving it as well.
cool, didnt know that, thanks, yeah ive definetly got the power to hit a high 10 second pass, again whether or not ill have the traction to get me there is a whole other ballgame, haha, gonna try out my 22X8X15's m/t's first and see how that goes then go from there up to a bigger slick if i have to. The thing that makes a good difference is the weight of the car since i can spin the slicks and still be accelerating quite quickly haha
i usually go to speedworld, they are more lienient there haha and not near as packed as firebird is. I can go to speedworld for one since its closer but they keep their track pretty well prepped and its usually pretty sticky.
Last time i went out on my t25 i ran a 12.4 on these slicks doing a crappy 1st gear burnout, preload at 4500 then rev limiter launch the car with the throttle to the floor, Netted me a best of 1.71 60ft and it just slightly spun the slicks in 1st, so i think track prep has a lot to do with it, That why i wanna try these first before going with a bigger slick. See how well they hold if at all. hahaha
New NHRA rules say 11.55 or faster needs a cage, which with a FWD street car isn't easy to do, no matter the power.
Either way, good luck to you sir.
I thought it was 11.99? Did they relax it half a second LOL?
and my sh*t still isnt broken in. Ive logged less than 300 miles ROFL. I havent even turned on the boost controller, high octane board, or the water injection and sneezed 400whp on 1 Bar and a sh*t tune LOL God damn Unicorns.

Im from yuma as well! I'm a yuma criminal(mascot for those who don't know)....so you come up to speed world huh? I'll keep my eyes open next time I go to yuma!

Yep. It's actually 11.49. Probably did that since there are stock cars that can do that now...

You need to just throw some C16 in there, crank the boost and see what it'll do. Santa needs his sleigh back...
What are doing for your traction issues ashtonsnissannx?
Tranny,clutch,lsd,traction bars etc....
right now im using a b13 trans that is dead stock with no 1st gear, ill be getting a p11 or b15 trans here soon, Im running a fidanza 8.8 lb flywheel with an ACT Extreem pp and 6 puck sprung disk, no traction bar, i have es bushing all the way around and ground control coilovers on gr2 struts.
Ive always had decent traction on the track, i netted a 1.71 60ft on my t25 setup rev limiter launching with the throttle to the floor after preloading at 4.5k rpms
Ah, had to edit since I went back and read, lol. I am surprised how much power it made for an untuned setup. Now I really wanna get my car on the dyno but it definately does not run as hard as yours. I am also wondering if that turbo manifold may flow better than a log manifold.

i can tell you right off the bat that this manifold flows better than a log manifold. Guaranteed, Its not the best tubular mani out there but it definetly outflows a log, It has a decent collector that for the most part smoothly merges the exhaust flow. The runners are decent size as well. The runner lengths are pretty short in comparison to other tubular manifolds but they do the job. If the quality were better i would keep it and im going to keep it on there until it falls apart to the point i can fix it, haha, I already had to repair the manifold once after the wastegate flange where its welded to the collector cracked and broke off completely but its now welded alot stronger than before and we went over the welds on the turbo flange as well. Should help out some as well as some bracing to help strengthen it a bit.
But hey it definetly works. Yeah i can wait to get it really tuned well but im trying to eliminate alot of other factors before i do so.
Now you got me thinking of replacing my fmax log with a tubular. Hmmm, lol. Not sure if it will be worth changing my IC piping, rad support, downpipe, etc for. Definately got me thinking if I can find a amazingly priced EQ mani. Great power bro!
not all tubular manifolds require you to really modify anything, if you can have one made like im going to you can put it basicly in the same location as you have it now, Just have to clock your turbo compressor housing differently it wouldnt be that big of a deal, You might have to have a different downpipe made but thats reletavely a small issue.
wow great numbers bro, i actually am in the middle of building the same setup except with a log mani. i just got my motor back from the machine shop this well give me the motivation i need to finish it up! now throw those m/t's on there and lets see some track times
