anyone ran 15psi or more on their stock LS motors w/ hondata??? post numbers and how long it lasted!

 

20 psi stock LS with a block guard 292whp 272tq 93 octane for over a year. Sprayed a 50 shot on it several times best ET was 11.6 @ 123 on the nitrous. sold the engine to someone else, its still running.

 

only 293whp?? i know people around here making that kinda power on 12 psi stock ls. but thanks for the info!!

 

Been at 15 psi many times with no problems. Brief setup: stock LS bottom/B16A head, V-AFC, stock obd2 ecu.

i want to run 18psi on high boost mode and just 12 for daily driving low boost. w/ stock ls, hondata s200, 720 injectors i'll be safe?

Small turbos suck.. the entire car was built with parts we had laying around the shop.

 

I'm running 17 psi on a stock ls longblock. 290 whp 242 ft lbs. its been about 2 months and i drive it every day no problems at all. i dont baby the car either.

Damn! where is all that torque coming from? post the dyno chart if you have it.

Wow man that is shitload of torque! Post dyno sheet if you got it

 

20 psi on a small turbo is like 10 psi on a big turbo but i bet theres a killer torque curve in there.

 

its an LS of course it has torque

12.5 psi 300 whp 270 tq

been running 1 bar for a while now no probs

 

bump. i know the size of the turbo matters. i have something similar to t04e ball bearing.

 

Ill try to find teh dyno.. I posted the buildup of the car over a year ago.. it was in SCC feb 03

 

isnt that your gf's car

 

bump

 

what size injectors are mosty of you running @ 15 psi?

i am going to run 720's

 

anyone feel that a boosted ls vtec can be as "safe" or as reliable as a boosted gsr?
Realy interested in the tourque from the ls and I think I can make good numbers. Im just scared about the head going on without problems

 

And How much boost on a Boosted Ls/vtec with a drag kit would it take for me to hit 350hp to the wheels?

 

not a LS...but im running 1bar on a stock internal b16

 

Lot of torque because timing was retarded

Thicker headgasket though...Timing is VERY conservative and a/f is 11:9
