Supercharger Dyno Graph Comparison

[StangJonGT]

After looking at some dynos for roots and twin screw, I wanted to compare them to a centrifugal (Vortech, Paxton) dyno. Anybody that has boosted their car, please post your mods and dyno graphs here. I am specifically looking for the graphs so I can analyze powerband and torque curves. Thanks!

ok

here is my roots blower..

its not a lot of HP but thats not what I care about I like torqe..

 

[StangJonGT]

It was actually your dyno graphs that got me interested in this topic. PSI would help too, as well as other mods. I know that is in your sig, but are you really running the full 9psi?


Jon

 

[WRXracer]

yeah

yes that is with 9 psi its not a lot of hp..

 

[Firemanz]

Vortech V2-SQ @ 8psi. Numbers in red are final numbers.

Here are my powermaking mods.........
Vortech V2-SQ w/ 3.6" pulley
Steeda powerpipe
Walbro 255lph fuel pump
42lb Bosch fuel injectors
Recalibrated 80mm MAF
Autologic chip dynotuned by Murillo Motorsports
Mac 70mm TB
Magnaflow side exhaust

Mods are in sig. Stock pulley.


edit.....Look down about 10 posts. I finally figured out how to post my graph.

Guys, its pretty pointless to just show the final numbers when comparing a centi and a roots blower...

Roots make a ton more power downlow, centi make a tun more up top.

 

[StangJonGT]

My point is exactly yours White360; I want the graphs so I can see what is really going on. Thanks for the input though.


Jon


P.S. TruBlu, what kind of boost you running? I need psi too.

Let's see....

My website is currently down but I do have these two vids:
www.diman24.com/videos/DeadLurkerDyno398RWHP.wmv
www.diman24.com/videos/boostguage.wmv

I'm currently at 398rwhp and 376rwtq SAE with the Steeda tune but I've maxed it out and plan to upgrade to 42s and a LMAF and then get a custom tune from Tim(Cobra Killer)

I'm currently seeing about 11-12psi but when we dynoed the car it was really cold outside so once it warms up I should lose some of that extra boost from the cold weather. I'm talking like below 40 temps.

My Mods:
-Mongoose Kit(Vortech SQ)
-Paxton Intercooler
-Steeda Powerpipe
-RR 3.3 Pulley
-Vortech Mini Race
-Bassani X Pipe (with cats)
-Bassani Catback
-3.73 Gears

I ran a 12.3 with only 363rwhp so I'm looking to get one 11 second timeslip something this year.

Kamran, was that with drag radials or street tires?

At first I wanted to run a 12 on street tires but the best I ever got was a 13.1@110mph with my factory tires, vortech(stock pulley) and bassani exhaust.

After that I gave up and got some BFG dr's and went 12.8s...then I got the 3.73s gears....opps forgot to add that ...and then ran 12.3.

Btw here is my latest graph:

 

[Firemanz]

Good numbers man.

I'm going to the track next Saturday for the first time and I already have someone willing to lend me their DR's for a couple of runs. I won't even bother making runs with the 18's on there......

It took a lot of practice and a really good burnout to get my times...good luck.

For you supercharger guys, will somebody see more boost if they open up the exhaust? I know you can get more boost if you open the intake, right?

Here is mine. KenneBell @9psi on stock block and saleen borla cat-back.

 

[StangJonGT]

Good numbers Texas--I didn't see a dyno graph though.

Awesome numbers 00s281--that torque curve is rediculous...if I could call that flat line a curve! It also looks like you have more power to be found past the stock rev limiter.
