a cool, least we have a reference figure now for running the smallest s475 possible

since enzo did 497whp at 17psi, we can probably guess that he is about 450whp at 15psi so if you wanted a daily driver your looking at losing roughly 50bhp but gaining 1200rpm in spool time, seems worth it!!

Be now interesting to see in the future where the max is on that little rear end, maybe 520whp

So the more 7's the better.

Me and catch-22 was hanging all day today. He made a new charge pipe for his setup. We were at BRE all day today. He was happy with how things turned out. We had planned to dyno also, i didnt have my car with us and by the time we got done and i went to get my car it started raining, and i dont have windshiled wipers. So next week we are hoping to see some results.
Nice little crew yall got. Imma have to get with yall. I believe i talked with you once on HorsepowerJunkies. So I assume the E55 belongs to Nevil from Lee's Performance. Tell him he can run but he can't hide. lol
Good luck with your ride and tell Brian(Rotorsports)that I asked about him.

Hey Ira, whats up man. You are a legend in my book. I met you a long time ago when u brought the corolla to rotorsports and had the block JB welded to fix the dowel pin leak.. lmao.. But Bryan always talks about how you pick that half dressed motor off the ground by yourself and put it in the car.

Yeah the E-55 is Nevil's. You should know the crew cause he normally runs with us. Local cruises and all the work done on his car is done by Nick (yellow turbo M3). My buddy zach got hooked on the blow thru carb setup from following you.

Hopefully we will see you up at z-max this summer when the track opens.

Yeah i'm impressed with the turbo so far. I know it will fall a lot when we push it, but im only wanting maybe 100-150 more hp. I think with a better tune it couldve been in the low 400's. I did three pulls. Catch22 had his laptop and pulled some fuel out. First pull was 378, 2nd- 383, 3rd was 394. And i think he was only taking it to 7000rpm.

Really we were just hanging out at BRE in concord and the dyno kinda came up so we decided for ***** and giggles to get on. I really wasnt expecting that much.

So we will see what the little turbo can do. 83 trim exhaust and .80 T6 rear housing.. If i can get the 550-600 out of it i will be more than happy.

Thanks man. I remember your monster of a car from waaaaaay back. I always wanted my tII to be a beast like yours.

I think the BW is a great turbo for the price. I can't give a comparison to any other turbo cause i haven't used any, but im impressed with this one so far. I'm waiting on my water injection kit then i will turn the boost up.

Thanks again for the compliment..

Hmmmmm, not really. Been enjoying the car. I drive it a few days out the week, when i wanna get high. Fumes are killing me. Someone said to buy a carbon monoxide detector and see how soon im gonna die.

I plan to hit zmax drag strip on saturday the 6th and just have a good time. I'm really getting interested in beefing up the rear of the car. Bushings, kazz, axles and maybe the rp launch kit. I don't plan to drag the car alot but i just want a nice and tight drivetrain.

Also i'm ready for a 20-25psi tune on race gas. Need to get the water injection kit ordered and installed. Man these cars are never done. But i will have videos soon from the track to show my 13sec time slips. lol.

Hmm. Should make Friday night hopefully. The FD just clicked over 400 miles today. Probably won't be boosting by then though. Still gotta have The Rotorsport boys tune it.

Saturday may be intresting as well. Although straight line is not all that intresting to me. But it would be nice to see more FD's. I get lonely.

Also just met another FD recently aquired by a guy near me. I will try to get him to tag along as well.
You guys planning on meeting up and showing up together as a big rotor group?

Yeah that sounds good. I think me, catch22, and jc are gonna roll together. So we will hopefully have a good turnout.

Hahahahaha. Awesome.

I ran a 12.9@125mph. At 15psi.. had to run the tires at 18psi to hook.
Still was spinning 1-2, 3rd held great, then spun 4th. Track got better
On each run, and so did my driving. I babied the car so I wouldn't break anything.

That supra was trapping 141 all day long.

Also I weighed the car.

2945 with me in it, and I weigh 225lbs.

So trapping 125mph, whats my estimated HP?

according to the calcs it saying at that weight your pushing 450whp, has there been any changes since you had it on the dyno?

With a perfect launch its also saying you could run a high 10, which when i factor the details for another car in the uk thats lighter than yours and is 470whp, the calcs are spot on
