I have been reading posts about different bolt on improvements, and headers seem to be the biggest place to make good hp. How much rwhp and rwtq can be made from a LT set up over stock manifolds? Anyone have any dyno info...before and after exhaust?

 

I made a good 40 RWHP peak from stock to Headers, exhaust, and CAI. If I get a chance tonight, I'll post the dyno graph comparisons.

 

Pacesetter LT will net around +/-25rwhp intake will net between 8-15 rwhp. Both will run about 500 bucks and are prob. the 2 most common mods for a good gain.

 

There aren't very many "bolt on" options for the LT1. Pretty much intake, headers, ewp, and a tune should get an m6 lt1 into the 300rwhp range. Add on rockers and you should be looking at ~310-315rwhp.

 

We have a car with just shorty headers and it made 285 with a4 and 2800. and 3.42.

 

Good info. Do you have any track #'s before and after LT's? I want to do LT's next but wanted to see what kind of real world results they had for others.

 

Let's not forget a decent cam

 

yea i have shorties, and there about to get yanked off for some longtubes... nice and make great sound but im all about some longtubes

when they were installed on my car they were actually proto-types for edlebrock.

pretty cool to know that i have the 2nd set of these headers ever made.

 

I can give you before #'s, they are in my sig. Thru manifolds and a gutted cat with a TSP rumbler cat-back---13.09 @ 106

 

the bolton record is 327rwhp & 354rwtq threw an m6. But this is everything available and not common. With a m6 car and every bolton should get you 315-320rwhp. Enough for high 12's @ 108-110

 

I'm pretty sure you're talking about this car.

Let's not forget the thread title...

 

No its not. More like 335 RWHP.

 

No, I think he is referring to Roadtrip120's car. Shon never dynoed his old bolton 97.

 

Is there a list of what's considered a bolt on?
