2. all the accessories for that (pushrods, springs, etc.)
3. DOD delete
4. ATI dampener
5. Larger lower OD pulley
6. Big gulp air intake
7. 2" ARH longtubes with no cats to factory NPP's
8. Gates belt
9. Racing timing chain/tensioner
10. ARP head stud kit
11. Katech billet oil pump installed
12. ECU/TCU tune with HP tuners software.

Should have work completed and car back by mid/end June.

Congrats on pulling the trigger... I am positive you will be smiling from ear to ear! Great starting point to build on later... should you stumble on another $10-15k in the near future

Baseline and final dyno's

Impressions: Vengeance is awesome. Excellent work, they keep you updated, reliable, car is a rocket ship. Every time I start it, I grin, smiles for days driving, listening to it, feeling it rock the car with the chop. 100% would do all this work again, plus I feel I've laid down some of the foundation to make big numbers later down the road.


What do you all think?

Congrats on the build. Enjoy it!

Also heads up... the top coolant tank needs to be full, not half empty (as shown in the last photo).

If you stay with the stock pulley and run a JMS booster u should be able to run e50+. I have a thread below yours asking the same thing lol.

I originally had similar mods still stock upper/lower pulleys, added DSX Flex Fuel sensor and JMS Voltage Booster and I ran E60 no problem !

Yeah, it was a very last minute change i had them add, I forgot to snap a photo. Good eye!


I also checked the coolant and it was topped off, from previous comment. Thanks all!

Great numbers, great build. And if you desire down the road, add some e and pickup another 50-60whp, if not more.

I honestly feel like this is low, but maybe im wrong... maybe was tuned conservatively with things like timing, boost levels, etc IDK. You can defintely run e85 with your setup but I feel/think with your mods you should be atleast 750-780 range...

regardless, (to me) 700-750 is the sweet spot for this platform. What's important is what you describe... that you love it.
