Went to the track last night and had some better results than previous. Being that my car chokes out with the stock intake at about 5000rpm I made no power beyond that point and at wot the car doesn't like to shift untill 6200rpm, 1200rpm of flatline, no power. Which gave me nice 60' times of 1.78, but 1/4 miles at 14.0 at 89.9 mph. So untill the new intake, I tried about 80% throttle and the results were a bit better.
60' times dropped to 2.10
1/4 ended up at 13.707 @ 102.32mph
Much better than before!!!!
Next project- redo my heads, bigger cam .550/.550 ++/ Along with the TPIS MR to help out the top end of the rpm................
I'm going to aim forthe 12'ssssssss
Later. FRED
P.S. I lined up against a friend w/ a 93 Mustang GT that he just went through with new heads cam and upper 1/2 along w/ 3.73 rear end and all he saw was my tail lights!!!!!!!!!!!! HA! Ha!
Yes, about the rpm, maybe a bit more up to but not more than 5200. The stock plennum/runners and intake manifold restrict the air into the motor toooooo much, but till the new componets come, I'll be happy with the 13.7 for now.
Till then, which should be around the fall sometime I'll have to live with those #'s.
By the way I also had fun eating up a modified s2000 on the highway on the way home from the track also. The Honda was pretty peppy, but had nothing to give after 120....................... SEE YA!!!!!!!!!!!
Before you drop that nickle on those pricy intake mods you might try the siamese base. Since you're going to replace it anyway couldn't hurt and might just be what you need to get your shift points into the high 5,xxxrpm range. I'm sure with your mods and some heads work it'll take you well into the 12s.
I cut a 1"x1" hole between each runner in the intake of the base (pics and method on my site) and added 20hp at 5,400rpm. As soon as I deal with some other issues I'm going to extend the depth to 3" and get another set of dyno pulls.
Thanks for the reply. I to have an 89 about to undergo reconstructive surgery in addition to the mods I have in my sig I plan on putting a cam and rockers in it. But first I must get trans rebuit. Do you like the 2600 Stall ? Is that what you would suggest for a basically stock l98 ?
No, I think that's a bit high, but if you are going to modify you may want to look into one.......... Mine came as part of the rebuild. A company by the name of Level Ten rebuilt my transmission and when I told them what I was going to do with the motor they sold me a 2600 stall TQ along with the rebuild..........

keekster, I agree on that TC. So long as you keep your low end torque (with a mild cam)you don't need to raise your lanuch RPM much.
I believe your stock TC is, like my OEM unit, only 1,500rpm. Since you have done gears a 2,000rpm TC will be plenty, especially on street tires. Even with my 2.59 rear and 2,000rpm TC I can now do a burn out at the strip without touching the brakes to do a little brake stand and pull mid to low 1.9sec short times. With this TC and your gears you will likely to be able to pull low 1.9sec to high 1.8sec short times.
