first time @ track since the new engine.

best time

13.3 @107.

11psi on my hybrid, shifting @ 6.5k because Im not tuned, running the stock topmount which doesn do crap.....

So all in all, very pleased with the run...

Ill be WAY down into the 12's once my FMIC is installed and I run around 17psi....

Very nice. Same questions as RX7withNitrous, plus what are the specs on your turbo?

..

Microtech with nippodenso fuel pump and 1100cc secondary injectors....

Hybrid is stamped as a Garrett. Its something like a t04 H3 trim is what they call it....should be good for around 350rwhp.

I also did the run 15 minutes after getting off the freeway and going through tech.

And with the large streetport on my new motor, all my power is up top. And shifting @ 6.5k is hardly using the powerband of the streetport. But I need to be a little safe until its put on a wideband....

Hell, a FMIC, 7 more pounds of boost, and tuning should get me at least 75 more rwhp. Right around 350rwhp. That should scoot me down to a 12.5 or better. With slicks, I might be able to push a high 11.....

RXSTASY ran like a 12.7 @ 107-8mph is what I recal, and at the time his car was only pushing 300rwhp. (dyno'd) I could of hit very close to a high 12 if my car had some time to cool down and if I got better than a 1.192 60ft.....I was having a hard time off the line.

replace 1 with 2

What 1100cc injectors did you go with, and how much?

How hard is modifying the stock fuel rail to accept these bad boys?

heh.....

yeah, 2.192.....i wish 1.192.....

I had RCeng modify (flow) my stock 550cc to 1100 cc's.... that means they will fit stock s4-s5 rails...1100cc is the max they can flow the stock injectors to.

I did a lot of research and this seemed like the best way....that way you dont have to worry about impedence and you don't have to worry about fuel rails..... RCeng quality speaks for themselves, they do great work.

Im really pleased with how its running, I just got to keep telling myself that my streetport/turbo/injectors are not even using half of the potential....I was just curious what time I would run because Im out of Money to get the front mount and a full day of tuning.

On a nice cold night, I beat my buddies mustang cobra/turbo that runs consistent 12.7 @113...

Very nice times. I need to get some bigger primaries and get tuned when my car gets out of the shop. I am going for 12s but am pretty damn sure I'll need more fuel even with my 720s maxed out.

yeah..

yeah, 720's will get you into the high 12's....but I wouldn't push it beyond that....


720cc secondaries can safely get you 290-300rwhp, but thats pushing it IMO to be safe. But 300rwhp will net you a high 12.

1100cc is great for a hybrid setup.. I can safely get around 375rwhp, probably a little more with 1100cc seconaries....which is like 425 flywheel.

Your car should be screaming.....I can't wait to get my FMIC.....

I think I may just go with 720s for the primaries as well since I don't have a standalone EMS yet. My car was alot faster even with the stock turbo. I can't wait to get it back tomorrow.
