How much HP can I expect from these bolt ons?
 

So I currently have a rotofab intake, solo high flow cats and a stainless works retro cat back. I dyno'd 522 rwhp/500 rwtq with just the rotofab, high flow cats, and stock NPP exhaust.

I am looking to install the following:
ID1050 injectors
Lingenfelter Balancer with 10% overdrive pulley
TR7IX Iridium Spark Plugs.
Custom Dyno tune.
Stainless Power long tube headers

Would all this get me over the 600 rwhp mark? And what IF i didnt use long tube headers? would my gains be significantly lower?

Thanks in advance.

You'll see 50-60 rwhp with 10% and a tune. Diminishing return above that w/o a cam and headers.

With an CAI I saw 559-580 depending on the type of Dyno, w/o the headers/plugs, less if you have an auto..

Since you have Headers, I'd concur with about 580 RWHP. 1050s are pretty overkill for a 10%, I'd just go with an 18% at that point, in essence a JRE 125 RWHP kit. I'm assuming you already have the intake? If not, add it.

Ok cool. Thanks for the input guys.
I figure the ID1050's because I can always add more mods later.

I did 1050’s with a 18%. Tune & rotofab put down 585/552 on stock manifolds. Headers should put you over the top..

Thanks for the input. I might just go the 18% route then. :thanks:

At the most, I'd say 75HP.
