Yeah I have been down that road before, I have come to the conclusion that it is not a specific boost level, but a power level when it does it. 21 psi on the dyno, compared to 17 psi under heavy load on the track. I am going to o-ring this time.

 

You mean before or after the k-member? Kind of tight to squeeze 5" above k-member

 

Great job Chris!! The guys up here in Michigan are pullin for you!

 

Great job man!!! that's definitely moving out..

 

Street cars have chutes? lol.

 

Congrats on your setup, car looks and runs bad azz. How do you like the BS3, do you tune it yourself?

 

thanks for the info, what was your trap @ 6200ish rpm? seems your rpm's are way up there for the mph?

driving on the street, what is the max boost you see, and when do you see it?

It has always been about the power level. I wonder if you can get a set of those gaskets or o-rings like they use in canada, I believe. A "pyramid " style head gasket or o-ring setup I think it is called? I had my old heads o-ringed and it helped out alot, but it eventually pushed water as well. How much timing are you at. It seems like 15-16deg. seemed to help out alot as well.
18 and over mine started to push water sooner.

 

Chute is easily removable
155mph, I have a boost controller, I adjust the boost all the time, as little as 8 as much as 21, full boost by 4000 or so.
I am going to be looking into orings this week. 21-24* on E85 and it was perfect for a long time, until we ran in cooler air, and 17 psi.
It pushed before at 12* on 93 and 118 cocktail. It always seems to be right around the 1000 hp level on this setup with the L92's.

 

Here is some photos from Friday....
This one if for the nay sayers, that a 3.0 gear wont work, 1.33 60 ft. 8 psi of boost on launch at 3500 rpm.

 

Damm Chris you got that bird flying !! congrats very impressive ! wish i was there to see it. You have came a long way you should be proud ! keep up the great work !!! SAM

 

Very nice man!! I have been following your build and you only keep impressing me.

have you thought about trying the L19 head studs? pricey but may be an option as well. I have a buddy with them and he is running patriot heads making 1000 to the ground with no head lifting. I'm pulling for you to figure out the head lifting problems since i am running the L92 heads as well

congrats again

 

Those are some good pics. I am going with a 2.75 gear in mine this time.
Your car is looking good!

 

Thanks guys, I will do some research this week on the head lifting issue, and weigh all the options.

 

Congrats on the new time! Car is hauling *** for sure.

 

Check with VINCE, he is goin bottom eight at 170mph and has a 4 bolt head setup. From what I understand he had very minimal head gasket issues?

 

dude those pics rock
those back tires are screaming help me LOL
im going auto for sure no more M6 for this guy

 

Shawn at Virgina Speed has a couple of tricks we are going to try.

 

I may be mistaken, but I think Shawn did Vince's motor as well? You are in good hand's!

 

"fairly" is what your calling it now?
