Dyno: Eagle/Vitara Y7.
 

Attachment 21648

Went over to Xenocron's shop today and got tuned. He spent a bunch of time to get the car right, and it feels great now. ------- thing rips. This is my 3rd tune with him. No complaints.

Setup is...

Y7 head stock with Aem gear.
Z6 block with Eagles and Vitaras. 75mm. Hone by yours truly.
Z6 intake mani and TB. No porting at all.
550cc rx7 inj's.
3 inch DP, no exhaust
Holset H1C. Full boost set at 23 psi. Doesnt get there till very late. I call it traction control >=)
Ebay 12x3x11 core fmic.
Homemade charge pipes. (Probably my limiting factor, 1 very sharp bend on hot side and smallish 2 inch bov pipe)
Anti-Lag building anywhere between 8-13 psi (Flames kick ass Chris ! Thanks)
Holley 255 lph pump.
SSauto exhaust mani, welded a couple times.
38mm WG with small and large spring and a MBC (Thanks Chris)
GM 3 bar map.
90 STD Hatch Gutted and cold inside, no heat.
Pretty sure thats everything thats important.

Say what you want about the #'s. I thought they were low too. But this thing on the street is ridiculous. Breaks tires in 3rd gear on demand and pulls through 4th like my 2nd gear used to haha.

In my defense Chris said my alignment/tires were fighting the rollers on the dyno and losing some power there. The wheels couldnt find a happy place and would pull all around. And I believe it because on the street it feels like more than 280 whp.

Flame away, but Ill most likely smoke your ass haha.

good ---- man

Re: Dyno: Eagle/Vitara Y7.
 

Nice numbers man! Did you guys mess with the cam gear at all?
I'm hoping to get that much hp out of my winter Y8 build.

Re: Dyno: Eagle/Vitara Y7.
 

Not bad Joe, did you ended up doing anything with the head? BTW why not just throw a z6 head on it?

Re: Dyno: Eagle/Vitara Y7.
 

Yea we did play with the cam gear. We ended up setting it at 0 because the dizzy was fully advanced for whatever reason.

Im pretty sure its the wrong gear for the head im using, but it works.

Head is stock, I like to stay away from the vtec heads. If I do end up doing something it will be a huge port y7 head with a regrind.

Re: Dyno: Eagle/Vitara Y7.
 

looks like some good numbers. is the z6 block stock no sleeves/filler? just rods/pistons?

Re: Dyno: Eagle/Vitara Y7.
 

Yep just rods pistons. I dont like to overdue anything.

Re: Dyno: Eagle/Vitara Y7.
 

then those are really great numbers then. how long do you think it will last? im getting ready to start the d16y7 block i have, im also gonna try to get a regrind on the d16y7 heads cam.

Re: Dyno: Eagle/Vitara Y7.
 

Haha hopefully a long time, thats the point of getting tuned.

Re: Dyno: Eagle/Vitara Y7.
 

I can't wait to see the new numbers, when you take it to the track. Are you going to put a LSD in it?
