Well we hit the dyno yesterday for some baseline runs. And see +/- how the cars A/F was. I was happy overall with the results so far but i am sad cause the Turbo its taking a dump.. After some runs we had to stop and unstrap the car cause the turbo blew the seals and started to have shaft play..the blades were hitting the edges and it was spitting oil thru the compressor inlet.

Now i dunno what to do..if i should rebuild it or just go with a better/bigger turbo..

Well on to beter news...
For those who dont remember here 's a quick rundown on the setup:

D16Y7 Block
Vitara pistons(8.5:1 CR)
Eagle Rods

D16Y7 head, 100% stock
Z6 Intake Manifold

LoveFab Manifold
T3 Super60 (.48/.60)
Turbonetics Racegate(42mm)
3" Downpipe and exhaust
Ebay Intercooler
2.5" charge pipes

First , the Temperature on the dyno was 88 degrees and the Humidity was 55%

Boost was at 1 bar (14.5PSI...spiking to 16 at some points)

we started with 217whp and 18X torque.

After 4-5 runs we stopped at 237whp and 198lb/ft

We did not touched the timing maps..Only thing done related to timing was set the Boost retard from .60* to .50*

Air fuel ratio on the dyno sniffer maintained under boost between 11.0 and 11.6

According to Uberdata my DSM 450 intectors are Maxed out after 15PSIs.. Around 90% and at 17PSI theyre 103%..lol

So i will see what i will do with the turbo, if i fix it or get a new one..Fix the Exhaust leak, wait fir the wideband to arrive and go do real tunning.. I hope i can get around 250-260whp at 15PSI


Dyno chart will be posted later when i get it..the printer on the dyno was not working so my mechanic got the dynoplot on a floppy.

Damn nice...
Im running your Vitaras in my JDM D15B right now. Havent hit the tuning real hard yet cause of suspension issues but i cant wait.

P.S. You could always just send me your old turbo and that would help your decision. lol

Forgot to say that all the pulls where done in 4th gear and it was revved to 6800rpms since its a stock Non vtec head .

EGT temps stayed at 1175-1200 F(EGT sensor in DP 1" away from turbo) at WOT and full boost in 4th

how long did you have the turbo for and where did you buy it?
my down2turbo t3 60 trim seals went and the blades his the housing

Had the turbo for around 5 months and bought it from the sooo loved TurboCalculator guys

i think down2turbo buys his turbos from turbocalculator

Here's the dyno sheet..It reads 233 cause of the "smoothing" line factor.

Nice

Those aren't bad numbers for only revving to 6800...

I would think you could get some more power through tuning the timing.

That's a nice torque curve too!

Yeah were gonna work that out next time..As i said these were just preliminary/ base runs just to see where the car was at.. We didnt had all the equipment we wanted to fine tune..

We'll try to smooth those lines and play with timing to get more power at the same boost level.
I llike the torrque curve too..it seem like it maintains the torque thru all the powerband..we just need to smooth it a lil.

Do you guys think upgrading to a bigger turbo is a good choice? Something like a T3/to4e 57 trim.. The Super60 seems to be doing the work done well though.

if you're interested
here is my dyno on 11psi

One of my best friends has been making 230whp and the same tq (mustang dyno) on a completely stock block for a long time.

And the point is? The above setup can be pushed a "wee" bit farther than a stock block

Good base #'s, good luck and keep us posted on what turbo you are going with.

AHH Hinfamous MJM auto - rebuild turbo s.. stupid POS's

Jockobo

go with a bigger turbo so we can see the limits of those pistons

Well money is an issue right now..I spent 300 last week on a wideband + around 100 more on a MBC and shifter bushings so the funds are low...If not i would get a t3/to4e 57 trim..

Things seem like i will rebuild the turbo, if the price seems reasonable..If not then i will try to get a new turbo..
Unless i find a money tree growing in my backyard

yes, to me for not carefully reading the first post and not seeing the word baseline duh

redzcstandardhatch

seem like really good numbers...

cant wait to get my bottom end together (same setup he is using, bought from fjt too)

just got the eagle rods! gotta save for random stuff now....good luck with the turbo man.

Jockobo

holsets are going for 200-300 on ebay...that would compliment your set up nicely...unless thats still too costly...

Yup... from a Suzuki Grand Vitara...

&lt;--- not kidding

I have some and will be installing them soon!

BME1986

Vitara pistons and scat rods going in my y7. t3 60 trim, and spoolin manifold. Hope to make some good numbers.

Tad

damn not bad,

i bet you'll be amazed when you add some more timing back into that thing

from what i've read about vitara setups, the low comp really begs for alot of timing.

joboost13

great numbers . I didnt know that the vitra pistons dropped rigth in like oem pistons did, that great advice 2 know . Cant wait 4 my turbo d 2 b finshed.

93formula

good luck with the process, im aiming for 300 with my vitaras
