this is a 3rd, 4th, 5th gear run. Max boost of 13 psi, and I know it is just tad lean. But how does my spool compair with some of you guys? 3rd I hit full boost at 4600 rpm, 2ed gear is about 5500 rpm, and first gear I dont hit 12 psi lol.

This is a t3 off a merc 300D, .48 a/r exhaust houseing, .6something compressor, begi manifold, 2.5 inch full exhaust. non water cooled.

Also, my intake temp hit 95 degrees in 5th gear, do I need to work on ducting?

Looks good to me. 95* IATs are normal yet not optimal. It all depends on your IC really wether or not you need shrouding to help. If you IC is too small to begin with then shrouding isn't going to help much. Any effort at directing air into the IC will not be worthless though.

18x12x3 ebay intercooler. I really dont have any shrouding now, so maybe ill make up alittle something. Now that ive got the fuel table pretty good, ill have to start on spark.

Right now its at 9.5 degrees of timeing at full boost, think I should keep it like that?

you'll enjoy a 15* angle much better, probably spool better and add about 30-40rwhp.

Just for points of reference, with my tiny exhaust and same turbo more or less, I saw 12psi at 4200. Then with my 3" exhaust and headwork - 3200RPM. Now it's closer to 3500-3600, i blame the larger IC.

alright! ill start on adding a little timeing, make a run and check for knock, etc etc.

Braineack

iTrader: (62)

yep, just be careful, but from what i gather, that's about the common place around 12-15psi (230-270rwhp).

When I went from 13* angle to 17* IIRC I made 20rwhp.

Seems a bit too high to me. I make full boost at 3000RPM on my SR20 T25. I advanced the MSpnp timing table 3 degrees and it really helped spool and pickup.

yeah, add more timing. I'm running a very similar turbo and make 12 psi @ 3200-3400 rpm.

cardriverx

iTrader: (12)

alright I aded like 5 degrees around 75 to 120 ish kpa, and I got the spool down about 300 rpm... ill have to do some more tommorow!

ark - you do have a 1.8l engine....

I think my turbo is alittle on the larger side for the 1.6.

what's the A/R and exhaust on your setup?

like I said, I have a 1.6L with a T3 Super 60 with .48 A/R. With my 2.25 Borla Exhaust I would see 12psi at 4200RPM, headwork 3900RPM, 3" exhaust 3200RPM...

Im 99% sure I rember right that the turbo has a .48 a/r exhaust hauseing, .62 compressor. It is a Garrett T3 off a merc. 300D. Oil cooled only, I rebuilt it. I have a sorta ghetto 2.5 inch exhaust, I had to bend it a little in places so im sure in some places its 2.25 inches. My spool is:

I hit about 8 to 9 psi in first gear

Just tap 13 in 2ed

hit 13 psi at around 4400 now in 3rd gear

Braineack

iTrader: (62)

no clue what I make in first gear. I dont even bother...and second gear I tend to break loose when I punch it...so, I always do everything based on 3rd gear pulls

my car actually stays planted in 2ed gear with crap tires, but then again I get alotta squat with the stock suspention lol.

Braineack

iTrader: (62)

once you get your 12psi back to 3000rpm you wont say the same.

cardriverx

iTrader: (12)

brain, could I see your spark map? I want to compair it to mine jus to get an idea.
