My tune..

I went to DB and had my timing around 20*, and I did not want to go any higher due to cylinder pressure.

We brought it down to 17* and hardly even saw a difference, so we left it at 17" as it's a "safer" level. You can run a ton of timing on E85 because it is just so damn knock resistant. But you have to be careful because too much can cause other issues.

I would say leave it where you are at, 19* is already a decent amount.

Just my .02 cents.

If you can't turn the boost up more then nitrous. Guaranteed more power with less lag too.

Haha. too bad I'm not a fan of nitrous.. But yea I'm gonna leave it be. 19 should be plenty.

[twack]

i got to vote nitrous, wish i never sold mine

[4g63tcrazy]

I already spin into 3rd with brand new tires. Nitrous would not help me in any way. Haha

[Halon]

Sounds like you need a laggier (bigger) turbo :D

[4g63tcrazy]

Trade S362 for 16g? Haha

[desolate]

I had a 16g and went to the scm61 on my old gst. It only made the car slower until boost hit, then berrrrrrrrrrrrr, wheel peel until you get to about 90mph. The wheelspin was actually worse on the bigger turbo. With the 16g, I felt that was the limits for a 1g fwd + getting wheelspin in check as it only spun for a split second (no lsd, 16x8s). Although big thing with a 16g is there is no top end (100mph+)

[4g63tcrazy]

Well it must be my 272's cause my car has massive top end. But yea, that is where the turbo struggles. I only shift my car at like 6300rpm.

One thing I've always wanted was a dual stage boost controller. That would be awsome..

[desolate]

I actually had bc 280s on it also. I guess my perception on topend is different. The topend I'm talking about is a 1.5 sec or lower 70-90 time, or trapping 130mph. Don't get me wrong the 16g has some breath, but when you've been in a 130+ mph car it's hard to say the 16g has top end.
