i am about to make another addition to my 93 R1, but am curious as what impact i can expect...i currently have an apex'i gt spec cb and apex'i intake...(and the other basics... boost gauge, turbo timer, etc)... i am considering a ss downpipe and the power fc...my question is this: what type of horsepower can i expect with these mods on a healthy engine? if there is any other thread that may help me answer this question, please point me towards it...thanks

 

good hp gain.. power fc and dp and you will wake up the car! if you are getting a dp and PFC might as well get a midpipe also.. that will have you quick!!

 

You should look into an intercooler.

IC good....IC VERY GOOD!

 

with dp, cb and pfc i did 242 on 103k mile engine at 11psi. whiterocket did 275, he has intake (among other things) in addition to my stuff and his engine is newer i believe.

 

thanks for the responses..any one else have input on what numbers i might achieve? if u happened to dyno your car with these mods, let me know what u got....or better yet, if you have time slips with said mods, let me know the results

 

With a DP and catback and 22k on a healthy motor ,I dinoed at 244.9 hp and 253 1bs of tourque.

Adding a PFC. and intake i got 286 hp.

When I put a midpipe on a few months later i got 293 at ten pounds, we heat sinked the stock IC. so we didnt turn the boost up,but figure about 10 hp for every 1b of boost and would have been in the 300,s. C.

 

wow, those are nice numbers, especially the torque. how much tuning did you do to the pfc and what boost did you run to make 286? what was the torque on that?

 

Used a base map. Tuning wise just ajusted the A/Fdown a bit ,from memory it was quite rich.
Tourque was 265. C.

 

Would agree with 93 blackrx IC. would be next mod,and possibly a radiator upgrade while you in there.

Then you can turn the boost up to 15 1bs !!
