8:8:1 compression ??? just a guess, your really making the turbo do all the work with compression that low. Turn up the boost

 

8.8:1 JE's.

 

BUmp up the boost, pretty good numbers IMO for the C/R your running the grph looks good turn it up to around 15psi.

 

its the low compression then... so how much you think i can handle 11-14psi???

 

If you can spring for it ($100.00) buy a Walbro 255lph and retune I would run 14lbs. You have the fuel, management and bottom end for it.

 

oh yea.. thats what i forgot i do have a walbro 255 is 14psi okay on stock head bolts?

 

Then I would go back to your tuner, unless you are tuning, and have him/her retune for 14lbs.

 

Jezz....I made 199.7whp and 135tq with my old N/A Ek hatch!

I am doing Turbo Si also, But i have decided to use the stock compression!

or you coulda ran the stock bottom end and made ~260-280

 

Give him time to up the boost

 

don't worry bro...i've got 8.8:1 pistons in my ls and i've got 155-160psi in all my cylinders and boosting 9psi i dyno'd at 210.6 whp and 193.2 wtq. i had originally thought i had 9.5:1 pistons until Boostfed told me that Ross did their calculations with a gsr motor/head which has higher compression. i also had my **** dyno'd at elite using uberchip and tuning with an afc.

well i would have, but i busted 3 ringlands off 3 cyclinders... but i dun know what i was thinking when i went 8.8:1 (there actually stock bore JE GSR 9.8:1 but im pretty sure they 8.8:1 on a b16a2)... but ill take everyone's advise and turn the boost

Hey that was me who gave you all the calculations! Give credit where credit is due! It took me awhile to do all those calculations.

whoops, sorry Boostfed...i knew it was boost+ something..., i'll go ahead and change that. thanks for helping me out earlier with those calculations!!

Its all good, i wouldn't mind have pistons/rods Good luck with more boost

 

how much timing are you running?

its stock timing... is that good or bad?

 

Why only 8-9 psi? With that turbo and that low CR u should boost a looot more. At least 1 bar id say. Its all bout tuning.

 

you arent taking any out per #?

left that to the tuner! your talking about timing right?

 

Turn the boost up to 14-15 psi and you will see a dramatic increase. why 8.8:1 why not 10.0:1???? hell even 9.5:1

Thats not true either. If they are 9.8:1 in a gsr they are something around 9.5:1 in a b16. I dont know what your problem could be.

 

It looks like it could use a little more tuning, but your low compression and lack of displacement along with the drag kit explains the numbers. The only way that setup is gonna make alot of power is with alot of boost...
