This is our first day tune on a Heffner Novi 2000 system w/AEM on 93 octane. All comments from resident dyno graphologists are welcome. [img]/images/graemlins/smiles[/img] To my untrained eye, it looks like there is room for a good bit more power over 5,500 rpm, and I really like the look of the torque curve. We can certainly up the boost some with a pulley change if need be, but I guess I better learn to drive what I've got first. [img]/images/graemlins/smiles[/img]

it's a great looking graph and that car will give even a few of the milder TT cars a good run for their money! :thumb:
I seriously doubt you'll ever notice that top end dip above 5800rpm - the power is so strong under the curve for a SC car on pump gas and no water/methanol injection. Great result.
Congratulations Red GTS! That is a nice looking graph. However I can not take credit here. All I did was mail him the parts. Have fun and be careful with that beast!
Tanked, as Jason said, that is correct. My Viper tech, David Yelensky, built the motor and installed the blower system, and John Reed of TorqueFreaks tuned the AEM. I was going to post some more detailed info after I got the car back, which should be this weekend. And Jason is being modest, as he did design the system, which is kind of a prerequisite to installing it. My hat is off to all three guys, particularly David, who was burning the midnight oil more than once on the job. :thumb: And last but certainly not least, thanks to Doug Levin, who served as an unpaid sounding board and advisor concerning various aspects of the build.
GoFast, until I get her back this weekend I won't have first hand knowledge, but my Viper tech thinks it's faster than his ZX-12, FWIW (I'm not a bike rider). I'm using the air-to-air intercooler that Jason uses, but UGR has proven that you can make big power with the Paxton air-to-water unit as well. That's another good example of engineering speculation colliding with reality, as I remember Dan Cragin posting several months back that the Paxton engineers had concluded their i/c was limited to about 720 rwhp.

Cuda, thanks for the compliment, but you'll be deep in the 9's before I could get my car in the 10's with me driving. I may need to take on the "team owner" role and get a driver for the track.

Yea Cudaman will be there very very soon. Now if I could only drive as well as Cudaman I'd have it going on.
Ronnie I'd be curious to see what the difference between the air to air vs. air to water is. I havn't a clue. Your gonna love the new power. We need to get together soon and beat up on some unsuspecting vette or stang owners

Brian, I don't think it makes a lot of difference with these two intercoolers and what we're doing with them. I've always heard that air-to-air is supposedly better for road course type stuff because it doesn't heat soak as readily, and air-to-water is better for drag strip use because you can add ice to it, but I think they both do a good job of lowering intake temps. And I'm all for getting together and blowing a few minds once I figure out how to readjust my driving habits to my extra 300 rwhp. [img]/images/graemlins/thumbs2[/img]
Brian and Ronnie you can not drive fast unless you have a car that is fast....
Both of you are smart let someone race the car that has lots of experience while you LEARN your car. The last thing you want is damage to your cars while obtaining that knoweledge..... experience comes with time and doing that correctly is what you are doing.
Drive your cars until you are comfortable with racing at the track .....it might take 2 months or 12 months.....time is on your side, you already own the beasts.
