well, your limitations are the turbo and injectors.....unless you upgrade those, you would be wasting your $$$

First of all, what is your current E.T?

I see one problem with your combo. And that is the chip. You need to get a chip burned by a reputable chip burner. A good chip will make a HUGE difference over a bad chip (not saying the ultra chip is bad, but there are others that are much better).


Remember that a stock un-ported head/intake motor will go deep into the 11's. When you get to mid/high 11's, porting the heads and intake will help. You should only port something when you are close to maxing it out. To me, it sounds like you should focus on other things than porting the heads and intake. One thing I would recommend is to replace the valve springs in the heads. If you have more than 60k miles, your stock valve springs are wore out. Replacing them with Comp Cam 979 or 980's will give you 2 tenths and 2mph in the 1/4 mile.

I'm going to the track Tuesday I will post my times when I get back from the track. My goal right now is mid 11's in the 1/4. I definitely want to change the chip also I have 1500 miles on the rebuild. I also have another problem my oil pressure at idle is about 15 and at wot about 40 it seems low to me.

Well, dont be dissapointed if you only go low 12's...

40psi at WOT is too low. I see 80. What do you mean by "rebuild"? New bearings I assume? What else was replaced? Who built the motor? What were the clearances?

 

[tonylukejr]

I'm hoping to do low 12's on tuesday night at the track my goal eventually is to do mid to low 11's. If I run low 12's on tuesday what changes should I consider to get to low 11's. I'm running 18lbs of boost on 93 octane with no knock, anything over 18lbs and I get knock. but I don't want to add an alky system. I was wrong about the oil pressure at wot its around 70. and to answer rebuild question .........ENGINE was completely rebuilt Bottom half of ENGINE completely balanced
NEW PISTONS and RINGS
NEW CAM
NEW KNOCK and CRANK SENSORS
NEW BEARINGS
NEW FREEZE PLUGS and SEALS.
All new parts were stock not high performance.

Thanks
