Going for more boost........... stay tuned!

 

Damn that looks pretty fun right there! Id really like to see what it makes from 2k up.

 

What is the ignition timing?

What fuel?

Did you have to run a different accessory drive to get the 2.9 Whipple to fit? Assuming a 5th Gen Camaro kit?

 

I think the tuner told me 31 degrees total. Edit: I don't know the timing!

Gas was 91 octane. No meth.

I ordered the 2010+ 2.9L Camaro tuner's kit. The Camaro uses the same drive dimensions as our trucks. You have the option of using the Camaro accessories or the truck ones. I use the truck one because I have Hydroboost brakes and modified the pwr steering/alternator bracket so it would rotate slightly towards the driver's side to clear the bypass and dbw TB.

 

Congrats on the #s John!! FWIW I just talked with Mike and your timing is NOWHERE near 31* under boost...

 

I was going to say the same thing, no way its that high.

 

Thanks for the correction. At my age I can't even remember what day it is. LOL This was my first boost motor so I am somewhat on unfamiliar ground.

I would like to add that my visit at Vengeance was a very positive one. The quality of work and the cleanliness of the shop that I saw really shows a high level of professionalism. Mike was awesome on the tune and shared his knowledge freely. I not only drove away with a great tune but also learned much.

 

Awesome, thanks for the info!

 

How much total boost do you want run?

 

Just enough to get me in the 500 club for bragging rights. LOL Want to stay under 12 lbs. to keep it reliable and useable.
