Heffner, DLM, etc. Why did you choose them?

2016 Views 23 Replies 12 Participants Last post by  The Viperjudge
I am interested in more hp but I want a good product at a resonable price(no HMS). So what were your deciding factors. Why did everyone go with their particular tuner?

Good and bad.

Would you now have changed your mind?

I suppose the first part of this decision is deciding on what kind of package you want. Do you want a NA car or a forced induction car. I chose to go the route of forced induction since it makes more ultimate power without nitrous. I ultimately chose Jason Heffner to do the work on my Viper since he offers a great product at an extremely attractive price. His products have demonstrated their ability to make significant power with superior build quality. Moreover Jason is willing to stand behind his products and has a great reputation. Do I have anything bad to say? Not one.
I certainly want to go with some type of blower setup. I like the way it looks and I think it is more reliable. I like to hear that some tuners actually stand behind their work. To me service makes sales.

Smokin. Just curious. How much hp are you going for? Intercooled or not.
My system is intercooled. For california Heffner was tuning for 700 rwhp on 91 octane gas. Since it looks like Houston is my new home now, and 93 octane is available. 750+ rwhp will be very possible.
That sounds like an awesome system. Would love to see some pics when it's complete.

Damn, what I could do with 750 rwhp!!! hhhhmmmmm
J Dawg,

I,as you,wanted more hp while retaining driveability and dependability. After speaking with various folks that had done work to their cars I decided to send my car to DLM. Doug builds beautiful systems that were easily maintained and he really stands behind his packages in terms of service and quality. Smokin' and I had many conversations concerning J.Heffner and I was very,very impresssed with Jason's work and reputation. I just decided that DLM was what I wanted. Both are very,very dedicated and extremely conscious of keeping the status of their reputations strong.
If you decide to go forced induction than you will probably want to go intercooler as well. You have a lot of folks on this board that you can speak with concerning a SC system. Feel free to contact me for info. on DLM.

I've driven DLM supercharged vipers for about 3 years. With serious HP, your ARE going to have issues. I haven't spent ONE PENNY. I repeat, ONE penny on warranty issues involving my car.

"The 1st intercooled supercharged Viper!"
Re: Heffner, DLM, etc. Why did you choose them?

I Chose DLM because of talking to folks like Gerald and other extremely satisfied customers. Since having the car back Doug Calls me on a regular basis to just make sure everything is going well. I Value his customer service do to the fact I'm not a mechanic and am basically clueless! I needed a car the was proven to be reliable! And that is what my 800rwhp is. The fastest true street car around my area!
Re: Heffner, DLM, etc. Why did you choose them?

Clark, good luck with the car.

Gerald and Dr. Roof. I've heard you guys have some serious hp. I'm reassured to hear that this much hp can be so reliable. That is my main concern.

Living where I live I know intercooling is key.

For me 650 rwhp would be more than enough.

Stupid ? but are these setups with only 1 s'c.

Thanks
John

Just one is all you need!

I would like to ditto everything said by Smokin V-10, he is right on the money. I chose Jason Heffner for the same reasons. You cannot go wrong with either one, you just have to talk to both, educate yourself as to all the possible options that exist and decide for yourself which one is right for the kind of performance you are seeking.
I will certainly give these guys a call, but does anyone know if they use the same type os s/c?
The current setup on my DLM car is a Paxton NOVI. The thing makes gobs of power.

I went with DLM 2 years ago b/c of Doug's reputation, his committment to service, and because of price. I've gone back for more twice now and Doug always takes care of his customers.

As for distance, Heffner and DLM are about the same for me. My initial conversations w/ Doug way-back-when made me extremely comfortable with him. Once I visited his shop (and he kept offering), I was sold.

I'd recommend DLM to anyone, and I don't know of anyone that has had him work on their car that has anything but accolades.

I would go with RSI. They've got some talented guys over there!
Can't go wrong with Heffner or DLM. I did the Roe s/c for several reasons:

1. Price, this being one of three hot rods, a boat and an airplane the $$$ line must be drawn somewhere.
2. Its quiet...that may sound stupid but I have another car with the beautiful sound of a centrifical s/c and I wanted no hint of blower whine on my daily driver. Its mean as hell but gets old after a while.
3. Its a do it yourself kit. No one works on my vehicles except for me unless it happens to be under warranty. You CAN trust these other guys with your car its just that I have a personal problem in this area.

Good luck, you are doing the correct thing by researching before you spend.

While not in the same horsepower league as others, on a stock motor it has turned in some very impressive et's....10.48 @ 137 first time out and they will be falling more in the future. I don't believe in racing "dyno numbers"
Since I have a 2001, what kind of boost could I run.
Dawg:

The good news is that you seem to be considering the cream of the crop here...for both product and tuner.

Like 1TONY1, I am running the Roe SC (2001 rt/10). It will allways maintain 5-6 lbs. (roots v. centrifugal). You also need to determine the $ you are comfortable spending. The DLM and Heffner setups are more expensive (to the best of my knowledge) while the Roe system is a bolt on. My guess (and others will chime in here) is that the Roe system will run $7,000 + install while the DLM and Heffner systems will run upwards from $20,000. There's a big difference! Roe yields 575 to 650 RWHP depending on secondary mods. DLM & Heffner yield 700 to 1000 RWHP.
My God you guys, I just blew this gsxr away yesterday, wish I had a camera.. My car is running the best it's ever run with my recent fuel system upgrade and new fuel pump upgrade. I swear it feels like another 50hp!! unreal!!

Gerald

p.s., whatever choice you make, you'll love supercharging, it's so easy on the engine and it's not beating itself to death at idle because of upping the compression, etc..

If you are looking for around 600-650 RWHP, the Roe system will do that just fine especially with the new VEC-2 Sean had developed with the guys in Sweden. I would also recommend upgrading to T&D's to stiffen your valvetrain as well as making a few more ponies with the Roe unit. But if you have the cast pistons, you might also consider going to forged ones as the cast ones have a very thin layer from the top ring to the top of the cylinder. I know Jason Heffner has some of the most reasonable "Non-Viper" prices out there for this type of conversion. I went all out on my project in the quest for ultimate power combined with OEM type reliability. You just have to decide how far you are willing to go and do it for the right reasons. :thumb:
I was one of the first guys to go with Jason Heffner's S/C system, and mine was the first of his intercooled system. Mine is currently the highest horsepower (844 rwhp) of the ones he has built, but I have a feeling that the current set of cars he is working on just might make more! If you see the massive intercooler on the front of one of Jason's cars, you will be amazed!

The reason I picked Jason was because I saw firsthand his workmanship and his attention to detail and his ability to engineer more horsepower. He listened to me about what I wanted to accomplish with my car and suggested a package for me. When all was said and done, he exceeded his promises and built a car for me that is so incredibly fast it makes your eyes roll back!! (Just ask Paolo! hahaha!)

Jason is constantly thinking of how to make these cars go faster with a high degree of reliability. He's the first one to tell you that if he's not comfortable with a certain modification in terms of longevity, he won't do it. Jason is an accomplished racer, engine builder, engineer, and tuner. And finally, his prices are the best in the industry bar none.

I drove by his shop yesterday (saturday, his day off!) and he had pulled all the customer cars out of his garage and was handwashing them because they had accumulated a little bit of dust over the past couple of weeks. The temperature was in the 30's! Now that's what I call customer service!

These are the reasons I chose Jason Heffner to do all the work on my car.

By the way, Jason uses Vortech superchargers.
