At 11psi I'm at 267whp, 237tq. Running 9.5:1 Endyn pistons with a Cometic Headgasket. So my compression is pretty low. Tuned with Uberdata. I was pretty happy with the results, I'd like to see 300whp but unfortunately I decided to run stock rods so I don't want to press my luck. I had some mild headwork done and I making peak power at 7500rpm. Weird for a LS head I thought.

 

What kind of turbo you using?

 

t3/t4 out of fmax kit

Cometic headgasket wont drop it down more than 9:1 compression. I don't know why u didnt just spend the extra buck and upgrade your rods when u already upgraded your pistons? Also, you are not giving your LS enough credit. Stock ls are capable of 300whp without breaking so I would turn up the boost to at least 14psi and shoot for 300 with proper tunning

 

Get some ARP rod bolts and up the boost. You will be fine at 300whp - 320whp with stock rods assuming you dont push the RPM.

 

The almighty LS engine. You gotta love em' . Congrats bro . I wish I had that much WHP

why didnt you change rods with the pistons?

 

turn up the boost. Engines dont blow up from X amount of boost. They reach a sertain HP level before they cant handle anymore. Keep cranking up the boosting and tunning until you reach your goal. 300 is very doable. Good luck

 

anyone pushing 300whp w/stock rods??

 

what kinda of dyno was it

not me, but I have seen people on this board make well over 300WHP on stock internals and they have lasted jst fine till now . It's really the tune and maintenance upkeep

BoostedCivicSedan is pushing over 300whp and 270ft-lbs with stock rods and ARP rod bolts.

 

I made 293 whp 230 something tq @13.5 lbs on a complety stock b18a1. It's runin great after 4 months and lots of passes at the track. id say turn it up some and you will diff make 300+. With a good safe tune itl be fine

 

its was a dynojet(no rollers), come spring time maybe I have to up the boost.
