What do do guys think my dyno numbers will be at with e85 ? Any experts or guesses lol I will post my numbers once I get it in the dyno

615

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.

Agree with tcm1 as he and I have almost identical mods and are super close in power. I’m auto though

@Rekkr @TCM1 thanks guy’s appreciate it , was thinking maybe mid 5’s but 600 is nice lol , car is auto bone stock , how does 600 feel in the street ? Does the blower whine louder with the pulley ? First Ima enjoy it with the mods then forsure add a cam and x port from Kong 🫣🫣

 

[Rekkr]

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

 

[Rekkr]

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

With out cam and lifters I say 605 RWHP

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.

 

[Rubber Duck]

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.
