NO bullshit please I need to know some honest stuff here.
AF is good: no higher than 12.5 and we are on C16 VPfuels race gas.
Current boost 25PSI
hitting 376HP and 361lb-ft

This is an LS motor with golden eagle sleeves, wiseco pistons, eagle rods, arp head studs, polished crank, balanced motor, cometic head gasket.
Drag Gen 3 turbo kit with drag intercooler and t3/to4e 50 trim 63 AR. turbo.

Can I go to 27 or 28 you think?

 

I would suggest stopping while you're ahead and not doing any guesswork. Call it a night.

 

So you think that I couldn't go past that boost. Golden Eagle said I am good to boost 40PSI on there sleeves. I am just seein for 28.

 

tuned on hondata.

 

???

Their rating for max boost is really subjective to a lot of things, tuning is up there on the list. My philosophy is, you've made 376HP @ 25psi. If you go to 28 psi and made 400HP but are closer to the limits of failure, that extra 24hp is really not worth it IMO. If you really want that additional power, I would personally look into improving other areas of your motor before worrying about bumping up the boost. Not many people are boost much higher than that.... Is this a race motor?

 

NO you are fine-- i would richen the A/F to about 12.0 maybe even 11.9 to be safe, and maybe retard timing in the upper RPM range a few degrees (say 2-3) to be safe-- once you hit your boost level then tune it out to make the most power

the most you can make with the hondata is 28psi, depends on the turbo but ive seen a T67 make 600+ on a GSR motor with hondata at 28 psi on GE sleeves.

 

another note is to let it cool sufficiently -- i lost 39 whp by heat soaking the motor on a few runs. turn it off let the fans blow to cool it then get back in and check water temps after a few.... once water temps are low enough ---- hammer it again on the same A/F see what happens.

 

391.6b and 376ft=lb so far on 27psi. going for 400 on 28 now.

 

did u break 400? good luck

 

395

 

damn--- so close yet so far away.......

 

I am gonna take off the power steering belt and let the shop cool down to around 50 before I make another pass. I think we can get to 400.
