Few races for the 1j

[psifactor]

your mph is low. I was running a mph of 104 with only an exhaust and intake. If you have the stock cams in there, right around 6500rmp is where the power band is going to start dropping off.(unless more boost is compensating for the loss of power at higer rpm's) So that may have been a good shift point for you.

btw, how much boost are you running?

I also have the fuzions in 275/40 and they are one of the best tires i have used. and I'm also using the 6097's at .028

screw it.

I have 3" Dp,
3" test pipe,
3" tanabe hyper medallion,
im running 17-18psi,
with a Sard ecu,
and a 264 exhaust cam,
titan cam gear on the exhaust set to 3* retard.
CAI sealed off from the engine bay.

i saw little gain from just the exhaust cam, i need a 254 intake cam to really gain anything.

i have a video of me running and in 1st you can hear the sputter clearly. ill try to get it hosted.

I know my mph is low, i know my et is too high. with a 2.00 60' i should be atleast close to a 12. hell a tuned 1j on 18psi and dr ran a 12.7.

maybe you just need some dyno time? or a wb for some fine tunning With that mph you are probably just around 300hp. Get the little issues worked out and i'm sure it will wake up the car.

at 17-18psi im way over 300rwhp. i had a good launch, good 60' then it would sputter ~7K so id shift, then go to 6500-6800rpm and shift when it started to sputter. best run of a 13.61 @102. thats horible for my mods. with that good of a 60'. with my ecu i go to 8K before it stops pulling usually. for some reason it only did that last night at the track.

the mph is always a good indication of what power you are putting out. This is why I pay more attention to my mph at the track than anything else.

Given the weight of your car (mosly likly similar to mine) and the mph, i'll bet you if you put the car on a dyno it will be right around 300rwhp. I definatly agree it should be MUCH higher with your mods but something is holding you back. either it running rich or having the IC become heat soaked quickly due to poor condition. Running properly on 18psi with the 264 exhaust cam I would think your car should be making more around 365hp.

Damn... from what I've seen I think you should be knocking on the door of 110mph. Change the plus they could be fouled if you've been running rich for a while, and like psi said, heatsoak could be coming into play. All I know is changing the plugs on my car made one hell of a difference, good luck!

nice kills and seems like you got some gremlins to get rid of. Wish I had a 1jz too...
