With a stock 91 Tbird SC you would be luck to see 200rwhp
i know....from the factory....they say 215 hp at the crank ....i want to get a base line from where im starting at....then i going and add a catback, 5% pulley, rasied top, SCP intake, and 75mm thorttle body and 76mm maf, a chip and tune from dave then back on the dyno......this will all happen over time..im not able to afford this all at once...lol...first thing i need to do is fix what is wrong with the car...then mod time
I say as long as your are running the ET you want, who cars about the numbers.
Port the stock exhaust manifolds, have an off road x/h pipe made(pipe before cats is a 90* bend)get the catback, 10% or nothing, the top is good can get them many places other than MP, forget the SCP intake make your own for a fraction of the cost, look for a 94 blower and plentum have it Sported, and get a double IC. With some sticky tires and gears, you should have a 13 sec SC.
No room for a x or h pipe...not with a 89-91 style gas tank im just gonna upgrade the mid pipe from 2.5 from the flowmaster kit to a 3 inch mid pipe........10% pulley is very strong down low... but up top it pulls timing as to not blow...... 5% pulley will be better for what i plan to use the car for.. yeah i planed on the exhaust manifolds but not for a while....... i wanted to do long tubes till i found out how much they cost....yeah i was told to do this.....my dad wants me to fix the things that need fixed first before i start with anything else..thats what i want..a 13 second supercoupe....
The most restrictive part of the exhaust is the collectors on the manifolds and the 90* bends before the cats, upgrading the exhaust without doing this first will do nothing. The only time the car will pull timing is if it detonates . The 10% with good gas and the right plug will be fine. But hey its your car do what you want.
