I was planning on it but I forgot my harness for the holley coils so I was using the stockers and I didn't want to risk frying the ECU. I just check my data logs and it's bleeding off 1psi through the pull.

Going back next friday with some of my issues fixed. Got my Holley coils hooked up so I can crank the boost and fixed my BOV so it won't open and I can get to max boost before 5000rpm. Then I am going to pull the air filter and exhaust off to see if it helps any.

I just took it for a drive with the BOV not blowing open and it builds boost much faster now. The data logs are telling me I am pulling through 2nd and 3rd gear .8 seconds faster than I did on my 11.1 pass.

WHy??? All talk

I made a mistake on the torque number it was 617 not 670.
First pull 161kpa bleeding down to 152

Second pull 142kpa bleeding down to 135kpa.


I need to figure out if my wastegate isn't closing. I'm losing boost and not getting to max boost until 5000rpm.

Back to the dyno tomorrow with 15lbs.

what turbo?
this 80 isnt fully lit on my car till 5k

That seems slow. I have seen the FI91 fully lit by low 4k's on a 5.7. I know it has extra displacement, but also a larger turbine as well as a T6 housing. I am really hoping to have my s480 spooled to 15 psi by 4500 with the 92mm turbine in a 1.10 T6 housing.

Good luck on the dyno today!

Thanks. It's a mpt70 with a .96 housing. It spooled up much quicker on my shitty 5.0.

Well I didn't get up to 15psi but I did manage to get it up to 13psi and she put out 587/697. I figured out that I had too much fuel in the acceleration enrichment. The car doesn't go rich when I whack the throttle and it gets into boost much faster now. I almost ditched it the first time I jumped on it. Throttle response is way up too. On the dyno the boost is bleeding down from 190kpa to 165kpa. On the street she holds pretty steady.
P.S.- 91 octane/windshield washer fluid at 14 degrees.

also what kind of tuner are you using? i really want to tune my own car..HP Tuner out of summit work?

I'm using the Holley Hp unit. It is badass. I've never messed with fuel injection before and this thing made it easy. Here is the dyno sheet. The higher number is 14 degrees compared to 15.

Here is a test on the street to see when boost comes on.

Well I have been driving this thing quit a bit. I must say that I'm an idiot for not switching to the ls platform sooner. I haven't had one problem with the car. It makes crazy power, gets 25mpg and I haven't had an exhaust leak yet. I may end up swapping the th400 out for a 4l80e. The car cruises pretty good on the highway but it's just a little bit loud. I'm going to fix up the exhaust some to see if it helps. I'm going to the track tomorrow night weather permitting with 587whp. Anyone want to guess what she runs?

SSZ

Man, good to see it running good for you. I hope you can get a 10.50 out of it. Do you think it is dooable

chiaj144

iTrader: (4)

With the power I'm making it better run that and then some. It ran an 11.1 with a shitty tune and 450rwhp and a horrible 60'. It ran 126mph so with a decent 60 I'm pretty much there. I'm really thinking its going to run a 10.0 if the track has any prep at all.

chiaj144

It ran a 10.502@130.19 with a 1.7 sixty. The track just wasn't there tonight (snowing). I almost put her into the wall twice. I ended up lowering the boost to 9psi and it held a little better. I don't have my shift light hooked up and I ended up shifting at 5600 instead of 6500. Best part of the night was getting called out by the fastest car at the track. I hadn't made a clean pass but I did get one good 1/8th mile in so I new I was getting close. I cut a .026 light to his .403 and beat him by 1.132 seconds. I hot lapped it and it ran a 10.566@133.16 in a 1.74 60, I shifted a little higher on this pass.

Here are a couple vids. They are just from my phone so they aren't very good or complete for that matter. First one I aborted and the second one I let out at the 1/8th at 106mph.
