I have a Built y8/z6 w/ Vitara's, SCAT Forged rods, Klevite bearings etc. I used to think I had a cam but after changing my intake manifold to a port matched and polished Y8 one with a 68mm tb, the idle is pretty smooth now. I have an ebay T3/T04E 50 trim and I made 303WHP Dynojet @ 19PSI. Its juts that the turbo is a POS and it vibrates and causes my fkn bolts to come out everywhere. So I want to get a new turbo. I think if I put a cam (like a bisi cam) in it I should be able to get like 350WHP on the same boost. And I think that would be enough, as I should be able to go into 11's with around that much power.
Right now it is on 22PSI and its fast enough for a street car, just not fast enough to compete at NSCRA (which I kind of want to do). Right now when the car is running right the turbo starts spooling around 3700 and hits peak boost around 5500 (when VTEC hits).

nihad; your times are bad because your short game is ****!

60fts are terrible

im willing to bet you shift slow.



get the 60s down to the low 1.7's and start banging gears and you should be posting much better ET's

no actually i shifted pretty quick.. Its due to not warming up the MH's... I just did rolling burn outs.. ebrake wasnt working rear brakes were bad.. car would just pull forward..

all friday i was launching at 4-5k and doing rolling burn outs.. tire pressure helped lower the 60' and q/m but not enough i was at 8-9psi.. Last run i was able to manage a 1.88 but the car bogged in 2nd..

Sounds like you aren't launching hard enough, and aren't riding first out long enough. 4k is too low to launch. Are you using launch control or are you holding the rpms there?


Are you sure there's an issue with the rear brakes? And if there is, you should actually fix that first before you take it to the track again. But i'm willing to bet that you are letting the clutch out to early when you are starting the burnout, and the tires are hooking and pulling you forward. Bounce it off the limiter then let the clutch out.

Werd, I launch at 6800 rpm. Doing burn out in 2nd gear and some time 3rd.

So I want 300whp out of my non vtec f22 stock sleeves rods and pistons. Doable?

No launch control just holding it i run it up to 5500 and drop to 4k.. i launch in between that.. I know i need more experiance... last run went from 1.963 to 1.88 with doing nothing to the car just a diff way of driving.. so i can see low 1.7.. Rear break is bad i never got smoke to come out from under slicks.. I wasnt preloading it with the ebrake i was preloading it with the clutch..

ferio eg

heres what i got with my vitara/eagle roads on 15 psi

Jimster480

not bad. What turbo? What head?

ferio eg

its a t3/t4 with only a delta cam and all stock z6 head

Jimster480

Just a regular ebay t3/t04? Or what size t3/t04?

you need to launch between 6-7k. you need to keep it in vtec and keep the rpms way up. slip the clutch and never let the rpms get below 5k. if that happens it WILL bog. keep the rpms up and ride out the limiter in 1st for a good 50ft or until the car speed catches up with the wheel speed, then shift. not doing that, will bog the car in 2nd gear.

as for burnouts, 2nd gear, redline or 2step until it builds boost...then drop the clutch. it will do nice smokey burnouts even if you cant use the e-brake. if you cant use the ebrake, try doing your burnout closer to the water...instead of doing the burnout at the edge of the water box...try doing it at teh edge of the water. without using the ebrake your going to have to build some boost and get that wheel speed up FAST in order to get good heat in the tires.

sohc launches are very tricky because of the tendancy to bog. spin to win!!

Thanks for the imput every thing you say is true.. I did my best at keeping the rpms above 5k because above 5k is where the power is.(vtec map) Now i did shift in to 2nd to early because the car got to 7.5k and i had to but next time i will hold it out till the tires catch up.. I did fell this in the car tires never caught up to the speed.. they just spin.. also remember i have a stock L3 si/dx trans..

with more practice that 1.963 turned in to a 1.88 and that would of eventually got to a 1.7/1.69

mr.bronx75

who was the tuner?

James from SF or Tony from Facetuned?

numbers look real good.

Here's my Speedfactory tune on 15psi



Last full pull we got was at 296whp, advanced the timing and the HG lifted so we didnt get a full pull. should be right at 300whp. ive replaced the HG i just need to get back in for a retune. trying to get to 400whp

ferio eg

they both tuned it

ferio eg

do you guys think i killed my car?

sohc-it07

both?

nihad

iTrader: (2)

Lets say its diff..

mr.bronx75

They both tuned ur car or did you use them at different times...

mr.bronx75

The bay is not the Washington norm but it is different from the OEM/JDM stuff that is senn all around that place ++ for being different...

ferio eg

first me and tony did the street tune....then at the dyno tony was on the car and the other guy was on the computer
