There is a sentra now in south fl making 600hp 25 psi afr @ 10.4 jim wolf ecu with stock bore block 35r turbo with no traction in 5th gear so before you wanna talk bout fl just take it easy cause we come hard and there are alot of 400 hp plus sentras that are not on this forum


I've never gotten to spin 5th because 4th always breaks before the tires rip loose.

I'm not downing on the FL cars, but there must be something special in those transmissions keeping them together.I finally bit the bullet and got a 6-speed. But its easy to spin tires and keep a tranny together in a 2200lb car. But us fat-car guys weighing in at 2670lb in my SE, and 2890 in the G20, can't even get down the strip.

That other 2L VE Sentra making 600 WHP on a JWT ECU would happen to be Gregs 4 door Sentra and I have done alot of work on the parts on that car. He even has one of my Alt in the back setups to.

The thing is people dont really know what is going on down here. I just post up on what is going on infront of me. I will get Greg to join the forum and post up his charts.

I talked to you about Greg's car over a year ago and I heard it had a GT30r making like 520whp or something on 18psi. I guess this is the Gt35r powered sentra?

I am in line for a GTX35r as soon as they get released, and I will be running the Twin Scroll setup with it in hopes of making the same power on 20psi instead of 26psi. But if he is running a GT35r it makes complete sense to me now.

i doubt he will, he dont even drive the car anymore. I saw the car after the dyno. Never saw a car rip 5th gear like it was second. I know the car is coming out in a few weeks for PBIR. Summer my project will be 600hp

See that's the problem with alot of people, they don't understand that alot

of people that are into "cars" don't even say shit on the internet, so all these

guys that see what people write on forums is all they know or compare to.

I know that your friends have made some good power on their motors, and

obviously made good power on yours also. Same as me, I've actually thought

about not posting ANYTHING about my Pulsar and the setup I am going to

run but then again I think about all I have learned over the past 10 years on

this forum and the old one then I think to myself that it's only right to post

what I've done and make for HP. Keep doing your thing Dre, and remember

that FL boys do it big.

Coheed,

Listen bro it has nothing to do with the comment being directed at me or not. You did BTW mention FL boys. Remember I may not live in FL anymore but, I will always be a FL boy at heart. That is where I learned everything I know and where my style developed.

Now I made the post I did because I found it funny. You implied your car breaks tranny because its making power... If I am wrong forgive me......

Now yes many of us have broken transmissions as well. I for one have about 10 of them under my belt. Now just to let you know my boy Gio (who you may have seen post here and I have spoken about) ran a P10 gearbox with a phantom grip and never broke it. Hell he is the same guy that is making just as much power as you are using 2 liter cams a a homemade log manifold that you are so highly against. His car is running in the mid 11's and has trapped in the 130's. Not too bad for a set up that is super budget "BUT WORKS". Hell when Andreas posted this cars figures you quickly assumed it was on race gas....... I have said it once and I will say it again your set up has always been very underpowered. I guess you can blame it on your elevation. Hell us boys from FL always get the "Your numbers are not corrected" BS but, for some off reason the cars always perform.

There are a lot of things going on in the VE world. A lot of things that this forum has no idea about. I feel that some people challenge builds way to much around here and what it does is that scares people away from sharing info. I know nice builds get posted and a lot of questions want to be answered but, it just seems like the attitude of some comes on a little hard. Hell it may just be the time of the month for me and I am sensative at the momment hence my long ass post. Who knows.

Dre made it a point for me to look at why my engine "only" makes 450whp on 24psig. Even if I could make more power, the tranny wouldn't hold it for longer than a couple pulls. My 740cc injectors are at 104% duty and MAF is reading 4.98V. Clearly you can see my setup is maxxed out, even though the dyno shows "only" 478whp. Dynos all read differently though. I just don't understand how you guys keep the transmission together. I baby my transmission compared to most guys and I always make clean smooth shifts. But every time I break a transmission it is in the middle of the pull (not on a gear-shift). With the MAF and injector readings I am getting it seems the car is making more power than the dyno says. 740cc injectors shouldn't max out at 478whp, and the maf shouldn't be maxed either.


I dont know how but I have yet to break a tranny at the 450 whp range on a stock b13 gearbox, but it has to do with how you shift and the type of clutch you have, also if you are breakig gearboxes dont you think a more linear powerband will make the car easier to drive and less stressful on components.Food for thought. responsivness is great but not always the best.

Couldn't have said it better myself..

These factory gears don't like that hard hitting torque..

Hence why I am stepping to a larger turbo. These transmissions have a hard time holding 400+torque.

I'm sure I will be making more power as well since I am running such a small turbo. You have had great luck with your setup, and I'm not so much convinced that it is an all-out power contributed failure. I feel the weight of the car has a big influence on the longevity of the transmission.

Also, I've tried sprung clutches, and lighter pp, yet they still blow 4th up.

The GT35 will at least get me in the same league as far as turbo sizing goes, where then we can start comparing numbers. Until then, the GT30r is a much smaller turbo than what you guys are using, hence the lower power numbers and higher torque numbers.
