Yes sir... However,on speed inc's jet it was 30hp higher then kirk and 25hp on hardcores. I been on both..I can only judge from two dyno jets i been on. and both were a nice bit higher then kirks. also,my new combo was way higher on a jet wich i was on a month ago over the new stang dyno i got tuned on. This new stang dyno is even lower then kirks. The numbers seem high on vengeance dyno and since i was buying a combo from them i wanted this guy to come and see the difference. so 30th,as you can see how dyno's very always have and will. If you want to add something pm me so we don't fill up this guys section with our dyno vs dyno vs dyno vs dyno.

 

Holy torque! That's a nice curve

 

Could you get that kind of torque curve out of a 402?

 

Absolutely...plenty of 500/500 combos out there

 

Honestly from everything I have seen Vengeance's dyno tends to be on the low side, they have taken a few cars over to dyno labs across town and they are usually lower. But it's 6-1 half dozen and the other, the car is what it is! Makes great power, drives perfect and it's a blast to drive oh and it's quick! So at the end of the day I really don't care about the numbers, Vengeance put together one hell of a combo!! They have built 3 different cars for me and this is by far my favorite! Yes theres dyno jet and mustang dyno haters and lovers, but my car put down what it put down and I am more than pleased! I would have been happy with 480 or 490, but it made 505 with me sitting there watching! Was a great day at Vengeance!!!!!!!!

 

Nice numbers! The torque is the key to having fun on the street. I agree.....Vengeance does great work!

 

Hows the driveability with this setup? Hows the gas mileage also?

 

What's the compression on that motor?

 

Best cam I have driven to date as far as driveability! It thumps hard as hell at the light but I can lug it at 1400 RPM in 6th and get hardly if any cam bucking. Drives smooth but sounds like a beast!

The compression is a bit high, I think we figured 11.9-12 I think dont quote me, I have had so many builds its hard to remember.

 

Oh ok. If I decide to go with a 383, I'll want mine around 11.5:1. I wanna higher compression but still safe with 93 octane.

 

The only reason mine is high is we decked my heads for another build, I was working with what I had! I ride around on 93. No issues!

 

Well that's good to know, but I won't be going that high compression.

 

I was getting ready to toss out the idea of doing a 383 till i saw this.

 

If your on a budget its not a bad way to go! Dont get me wrong its always nice to have more cubic inches!

 

No substitute for cubes, this is very interesting, 99% sure I'm going to get my 241 heads hand ported by a very reputable head and performance head specialist near me, but also been thinking a set of tfs heads for my 02 ls1 n/a 383 stroker, also nice numbers, has it been at the track yet?

 

Also want to get exhaust and intake match ported to heads if possible to maximize the potential but will discuss how much and if worth it for a street car with the machinest.

 

It has not been to the track yet, I am currently finishing up the VE table for around town driving, not to mention tires are gone! If it ever hooks up it should be a nice 11 sec car. I tend to break **** when I go to the track so I dont do it very often.

I actually do not have my 102 ported, My heads are CNC'd, a 102 on my motor as well as the 100m TB are complete over kill but, with that being said I can flow more than the motor can take and eventully when I get tired of this set up I will have the bolt ons for the next BIGGER thing! Got to remember though, if you get the air in you have to get it out!

 

SAE numbers?
