Awesome!!! Can’t even tell there is a 1000 horsepower under the hood driving it and it passed emissions!!! Lol
Awesome I was initially gonn aget my engine built Accufab but ended going with MPR TIM we will see how it comes out as it was more expensive than Accufab haha

Running flat tops for 10.3:1?

Would list part # but not on paper work.
Get rid of the Twin 67!
Get a SCJ or better, thank me when it picks up almost 50 rwhp. The Twin 67 kills 25 rwhp on mild 2.3/700rw combos.
Flat tops on stock heads and unmodified block deck is 10.2 to 10.3
I was told that twin 67 was good for up to 850 hp. I like the drivability as it is. Also Nice to have room to grow!! Some day I may make the few upgrades to add an additional 200 horses. Lol.
You were told wrong lol.
Or proved them wrong!! Lol.
Nope. Twin 67 loses 25 rw to the Super Cobra Jet @ 700 rwhp with a 2.3.
Ditch that twin 67, pickup up 30-50 rwhp.
You might make 1000rwhp with a Twin 67, a mono will make a lot more with every other variable the same.
Good question but I believe oem
No shit! I have a 2.4 pulley, full exhaust, cai, and twin 67. So I would pick up 25rwhp if I switched to a Super cobra jet TB?? Just dyno'd 673rwhp
The issue with the mono blade is there is a good chance of having driveability issues. Not saying a good tuner cant tune around it. But most have issues, I tried a mono blade on my 14 GT500 and Lund couldn't get the car to run correctly so back to the twin 65 T/B I went. Even with the twin T/B I still make 727whp and 798wtq.
Yes, with the same ambient temps you will make right @ 700 rw with the Super Cobra Jet, and pick up almost 1 psi boost.
Did you send it to Accufab to fix?
That tq number is crazy high. You are probably 727/720 and +/- 20 on the tq
Man I always come back to the throttle body upgrade question. I'm ~ 780rwhp/740rwtq w/ Whipple Gen 3 2.9 @ 19psi on my 2013 pump gas tune still running the VMP Twin 67mm TB. Drivability is PERFECT! Monoblade likely makes more peak power but will I kick myself for going backwards in drivability? And which monoblade works best for a streetcar....Whipple 170mm, FRPP Mono, or ??? And why the hell can't a manufacturer make a larger twin TB that idles well, has great part throttle/drivability, and supports big power? I tried an L&M Twin 72mm and it would not idle/drive. Is the TB gain/risk really worth it at my power level? Also adding an E85 tun w BAP this Fall.
