Went to the track last weekend in the car for the first time with the new setup. It was 80* out and humid but overall happy with the car.
Its a 92lx with a forged 281ci 3valve, stock heads, stock intake/t.b. , mmr blower cams, Paxton novi2200, 3.0 pulley 10% overdrive, 60lb injectors, 4r70w, silverfox full manual valve body, ptc 3000 converter (needs to be 3800-4000).

Car went the best of a 1.65 60ft, 6.88@103 in the 1/8th and [email protected] in 1/4.
Hoping to change the converter and go to some id1000 injectors to run e85. Goal is to get as close to a 9.99 as possible on pump 93 than run e85.
Anyone have opinions to speed it up? Intake? 3inch exhaust? etc etc.

Did you datalog to check your iat's to see if it was pulling any timing? I don't know much about centri blowers but the first thing you need to do is get that 60' lower which I'm guessing is the converter. Also, are you leaving on a trans-brake and 2-step or just foot braking? I also agree with the previous suggestions of getting a good intake and throttle body on it so it can breathe better.

As far as exhaust I don't think you need any bigger than what is on our S197's which would be 1 3/4" long tubes and 2.5" pipes.

My car weighs 3940 with me in it and running 8-10.75psi of boost mine will run 10.5-10.6 in ok air with 1.45 60's but I have an 11:1 compression engine, frpp stage 2 heads and E85 with an edelbrock tvs blower.

He didnt datalog it (forgot the laptop at home) I am pretty positive it was pulling timing as hot as it was. And no trans-brake on the car he was foot braking it. This is my brother in laws car.

He is running 2v longtubes that have 3v flanges that he bought from summit I believe welded on them.
If headers have been covered, add more boost. Ford racing intake and throttle body would be my second choice.

How high are spinning the engine? You should be making more than 18psi with a +10% and 3" blower pulley. I'm making 20psi at 7K with with a +10% and a 3.4" blower pulley.

Make sure you are not getting any belt slip and as other have said loosen up the converter.
