We have the same setup minus the upper pulley (mine is 2.4") and I'm not sure if yours is manual. 627/669 Mods in sig. Tuner said on E it just wanted to keep making more and more but he's all about longevity.


All dynos and conditions are different blah blah.

Blower whine is definitely loud-ish. I ended up swapping to a Kong ported blower recently.
600 on the street is decently fun. More than enough to get you in trouble. My usual thought is that for MOST people, 500-600whp cars are plenty of fun if you plan to just drive it on the street and occasionally beat on it. A lot people THINK they want/need to 1000whp , when in reality they find out it’s pretty un-usable in most street applications

A lot of people want 1000whp until they get the quote. Then most decide a lower number fits the budget better

Lol also that. Most people don’t understand not only the budget to build a 1000+whp car (correctly) but also the budget to maintain the car at those power levels

Honestly, it's pretty silly to me. This is definitely the fastest car I've ever owned. Add a tire to your budget. I'm on NT555's and can't get any traction until 4th gear, so hardly usable on the street. With that said, I guess I have no idea how fast the car actually is since she blows the tires off constantly (which is my favorite thing to do).


I have cutouts with turndowns so I hear that more than the blower but the whine is definitely there. Toss an intake on and you'll hear it plenty.

I Calc that 647 would be the ‘Safe’ best.

Most likely will be between Matt’s 615 to 636.

Mostly going to depend upon the quality of the fuel and tune.

Put a 228° duration cam in it, along with 271 cc heads with a good blower driven through a proper pulley ratio, and you’ll see the power go up at least 100 hp using a quality E85.

Net lift on the cam, less losses such as pushrod deflection should be around 0.540” to 0.560”. More is not always better here, depending upon cylinder head flow.
