Hey are you running an oil cooler?if so what kind,also I picked up Bosch ev14 630cc injectors for a great price

I have the 25 row oil cooler from Z1 .... It seems to have drop oil temp 15-20 degrees on my daily driving ...... I haven't seen it go over 225 in 80 degree weather... that's the hottest it's been since I installed it. I'll have to check it out in the summer.
I use the evo 650cc injectors ... You should be ok with the 630cc running 10 ish psi after that you might be maxing them out ... Not sure if the limits with the injectors. Jon at Z1 told be 600cc was more than enough but I opted for 650cc per install instructions ..... And really the more I delt with Jon the more the worse it got ... Terrible customer service/lies/....tunes he sent me were awful...... He seemed great until after I paid the money then it was like pulling teeth for a response .... It's been waiting 2 weeks for a tune correction that he promised that same day .... I gave up and started looking for another tuner.

Sounds like your having some bad luck with z1,I had contacted them a little while back about tuning and couple other parts,I wana stick with ecutek I think,the gamma turn key comes with 600cc,the Bosch ev's seem to be rated the best for over all in town driveability from what I've read up.Got a great deal for brand new,630cc n 650cc should be good up to 600hp I'd imagine depending on tune,maybe even a little more hp's

Getting close

tiller

Ya its getting there,I've got tons of time to complete,hey are you running the 600cc injectors?hows ur tune and hows it run with that size?iam lookin 725cc maybe so I can go up in boost in future but I don't want it to be too much fuel and ruin idle n drivability

Jinxx

I'm using 650cc with 11lbs pull idles fine .....has a very slight bounce like 30 rpm ...but I thnk is from the bpv ........ All my data logs seem fine ...I sent them back to z1 to review and tweak the throttle lag out and the fan tables ...until I can get it on the dyno

tiller

What size pulley on the pump are you running?

Jinxx

I'm not sure of the size it's a stage 2 and I was told 11lbs .....92mm I think ...I still have to install the boost/afr gauge and verify my boost level

fryzia23

11lbs pulley its 88mm. I have that on my stage 1.5. 92mm should be around 9psi I believe

Ya I think you guys are right,8-9lbs is 92mm pulley,that's the size I have I believe.

Bigger pulley means more boost correct me if iam wrong?wonder if they are carrying bigger pulleys.The vq engine can handle 11lbs on stock bottom end as long as you monitor properly.

jwick

Other way around. Smaller pulley means more boost.

Correct, SC = smaller pulley more PSI.

Ur right, smallers is more boost,so 88mm which I think was next size offered would mean around 11 or 12 I'd imagine,wonderful if there carrying them still
