That's ridiculously lean!! 10.5-11.5

i dont speak afr, only lambda.

It's nice to see this car finally coming together. A little more time on the dyno and it will be good to go

Also fwiw, no pulls were made at 13-1 a/f ratio.

I'll update this thread next week with final #'s and dyno sheets.

I made that post from my phone and only wanted to type 12 not 125, sorry

What AFR are you running

DSteck

I run 11.4-11.5 at 12psi. I found no gain in power with a leaner mix, but had smoother power.

A bit of good news for you...

With 454 CI, the cam profile you specified, the Compression Ratio you listed and the turbos you listed, You'll max out those turbos before you need race gas........ You should clear 1050 RWHP on pump gas NO PROBLEM!

Extreme u sent me pm but u dont accept pms????????

Sound like a nice project, but quite the ordeal, glad you have deep pockets to see your project through!

Sucks that you hooked up with so much incompetence at the start of this project.

Make me feel blessed that I have a best shop in Canada less than a couple miles from my home.

Good luck with any further endeavours!

extremecorvette

If I did my math right lambda would equal 0.81

For some reason I'm not able to get PM, I contacted two administrators about what the issue is. My inbox/send is not full and I have the options set to receive PM.

I found a few more pictures to show everyone.

Dyno numbers are up

Updated on 10/3/11

Well Jim spent all day last Friday and even stayed late to get the car done.

Jim set up the boost controller with presets at

SP1 6psi 592rwhp 573rwtq dynorun 25

SP2 9psi 690rwhp 654rwtq dynorun 27

SP3 13psi 815rwhp 803rwtq dynorun 31

SP4 15.5psi 878rwhp 899rwtq last run on 110 Oct Fuel

turbotuner20v

why does the torque (and hp) fall off so hard on the final run?


run 3 looks great though

extremecorvette

I was wondering the same thing myself and Jim is out on vaction so I can't ask.

Great build! More videos please. Also have you played with boost by gear or are those just presets? Lastly how's it hook at 9psi?

extremecorvette

No boost by gear takes a lot of work to get it to work and Speed Inc talked me out of it. If someone would just come up with one sensor that would be able to communicate with the boost controller I might do it.
I live 3hrs from Chicago and I’m heading out this weekend to pick the car up. So I don’t know it hooks up with 9psi yet.

Slo-Poc

Your boost controller is one of the better boost controlers that is able to do bbg. I would def give turbosmart a call and findout what need to be done. Spinning 1,2, and 3rd all the time is just not fun to me. But how you have better luck on the 18s. Ill let you know if I get any more info on it also.

extremecorvette

I will give turbosmart a call and see if they have come up with anything yet. I went with the 18" to try to help with traction and maybe I should have done 16" in the rear.

Im interested in running an APS kit what sort of oil and coolant temps do you see? How have you liked driving the car?

FloydSummerOf68

815 on pump gas seems really conservative for such an involved build.

It seems like that motor should be putting down a lot more power?

Very nice build though. I bet it feels great.
