Ok i have a 92 SSEI and parts ive ordered are a hypertech thermo runner with the 160 degree t-stat, a flowmaster 80 series muffler and a dynomax super cat, with just that stuff right there how much do you think i would gain? And also what kind of performance would i gain from performance plugs and wires, and sorry im a real newb when it comes to this but what information can you give me about performance injectors too? Thanks

You wont get anything from the T-stat, but a 180 would have been better, 160 is for heavier mods.

Exhaust 10-12 at the crank, for real power you need to do an intake as well.

Plugs and wires will help, but thats all part of a necessary tune up anyway

willwren, Jeffery10x2 and even Turtle SSE can give you the downlow on injector mods

Hmm someone told me that the exhaust would be more like 30-40 but since you guys already did it ill believe you and is there any posts that go into detail on how to make an intake because theres a few that briefly describe it but im not too sure on what to do still sorry if im annoying but this is the best site ever.

You will get 30 - 40 with exhaust headers and a proper cat back system.

I assume your thermorunner is a chip? I don't know anything about it unless that'* their standard chip. Expect 15-25 hp from the chip assuming you have supporting mods.....that means a FULL tuneup, intake, exhaust, and thermostat. Your 160 may be required for that chip, but I still don't like them.

Without an intake to go with the chip and exhaust, you won't gain alot. With the intake, exhaust, and chip, I'd put you at about 40hp in gains tops.

I've got the same chip and thermo. I like the setup. According to Hypertech, the 160 is required, they say to reduce knock retard.

The exhaust will probably be right around 10 crank hp. The Thermostat will help with Knock retard and keeping the engine cool (supercharger creates ALOT of heat). I'm not sure about the chip, but maybe 15 crank hp?

Injectors really aren't needed with little mods. Next you should think about a CAI and a smaller supercharger pulley (more boost ).

Post your car trim and location into your profile signature, add any mods you've already done it helps with giving advice.
A smaller pulley for sure, best bang for your buck.

Larger injectors will give u a performance upgrade but im not really sure how much because i havent had mine dynoed yet but i can tell u that they do make a large difference. I got mine from zzp.com. If u choose these be sure to get the afc along with them. The formula for figuring out how big ur injectors have to be to keep up with a certain hp demand is the injetors size times ten for a supercharged v6. I have 42lbs/hr injectors so mine can support up to 420 hp although i dont really plan on getting that much out of the car.

Injectors will do nothing for hp unless you have bad injectors to begin with, and only because you regain what you lost. They give you the CAPACITY to mod further, but do not by themselves add performance. Your stock fuel injectors have the capacity to carry you well into the mods.
