weak part, im gonna geuss the pistons and piston rings. dirttrackracers rods just failed too

 

I am over 600hp, I had it knock pretty bad on me the other day I was messing with a ssr. I forgot I had the boost set at 20psi and went over 4500rpm ( I start to lean out at 4500rpm @20psi) I am very surprised that I did not blow it. It is still running strong. I think they are stronger than people think. But we will see how long it will last. Next mods are the KB boost a pump and sd tune and a 35 shot out the hole. I know I am crazy. I admit I am a hp junky! I just want to try something that no one else is with the sts kit. NOS, just a little bit.

 

yeah, 35 today, 150 by next week

 

doesnt that happen to everyone, a little now, ALOT more sooner than expected

 

Yeah! you are right! I remember saying I just want 450hp and that would be it. Ha!

 

I just snort a line or two now and then.

 

Yeah, I bought my truck and was just going to put the Radix on it and a set of headers maybe. That was a year ago, 14k miles on it and going on it's 3rd engine!

 

yeah i agree pistons are proly weakest point from what i have read.

 

I also worry about the stock rod bolts!

 

i guestamate i have about 500 rear wheel hp by my times. 150 shot on a 5.3. i have sprayed a 200. our cranks will hold a lot of power. rods and pistons are what i would be concerned at when trying to achieve 600 hp.
