Looks like I'm going with a Large Twin Screw. Due to the fact I have such a low CR( Running -21,1cc dishes)It looks like I don't have much of a choice, not saying Twin screws are bad I just haven't found a kit I'm to happy with. Most Kenny Bell blowers don't have the inter cooler set up I'd like to run, in particular a 3-Core Air to Air. And to date I don't believe Whipple has a kit I can use without swapping out the intake. Saw a video with a guy running Whipple's 3.4L on his 04 Mach1, guess what's happening to the shaker. Originally I was wanting to run with a kit from Procharger, in particular a D1SC or F1a but the CR seems to conflict with that in the sense I won't be making enough power down low. I've given a single large or twin Turbos a thought but I am driven away at the thought of the complexity and necessary maintenance they do require. So I'm left asking what other option could be available to me... anythings a thought. Thank God I have time to work something out though.... Time won't ever be an issue here.

For forced induction turbos have been proven to be the most efficiant. What about a turbo setup makes you weary of that option?

[Techniq]

Not exactly sure. I'm doing a lot of the work myself w/ dad and I a hear there just a bit more complicated to install, were confident when it comes to the whole engine but when we begin with the forced induction area its new territory for us. Truth speaking I wouldn't mind going with a decent Twin set up from Hellion. Just with a low the CR wouldn't I still be in the same boat as with the Procharger? The car would still be a bit sluggish off the line but then again I'm sure all that could be solved with a rear gear change.

[Cricket]

If your going to be launching at the track have it setup so you can launch in boost. That won't be sluggish at all. I would go with twin turbo setup.

[Techniq]

The twin T66's from hellion wouldn't be such a bad idea. I'll be looking into it a bit more. Like I said I have time.

[Mach Boy]

If you have the know-how to take an engine out of a car I don't know why you wouldn't be able to put a turbo on. You'll have to get it tuned somewhere, but you'd have to do that with a S/C anyway.

[rk_2000_Z/28]

A complete kit from a reputable company like Hellion is going to have everything you need plus instructions. It'll be tough the first time because you are learning, but it seems as if you and your dad have the knowledge to get it done.

[Techniq]

I'm sure if we put our heads together it's something we could put together, I'm not one to half-ass a project so It'll be done right the first time. I'd much rather go with the TT's as oppose to a large gas guzzling Twin screw. As for the tune I'll be looking for an SCT tuner somewhere in Central Florida.... I believe there's one in Winter Garden.

[TRMach1]

What exactly is the final cr going to be that you think is too low?

[Techniq]

8.0-8.5. Talked to another person on a different site and a he stated that a -17cc dish would put you at about 8.5. Mine are -21.1cc. The head's will still be stock so I won't pick up anything there.

I was just curious. I'm running 8.5:1cr, which people told me was too low, but I have to disagree with their assumptions.

[Techniq]

But your running a Twin screw so your making boost pretty much right off idle. My original plan was to go with a large procharger.If an 8.5:1 was to low then what would be the point to go any lower?I'm sure a stepper set of gears could be an option to make my car a little less sluggish off the line. Then again as Cricket said launching in boost, with a Twins should do the same. Although a set of Twins might be a bit stepper in price it seems to fit the profile I like, which is that of a sleeper and a win from behind.

I see your concern and I think your on the right track I see you will be running 5.0 block which is great. But first off I say go with set of mild cams to start off with. You also need to ask your self what times you want to run on and off the track and what is your goal with your setup. I dont understand what is the problem with going with a 3.4 whipple or 2.8 Kenne bell instant power and instant boost and on 5.0 you can make 800hp on pump.
I myslef would never run any centrigufical prochrager or vortec they are very inafficient, all ways run hot az hell, and the way they move the boost is just retarded. If your going to go with twins which It looks like thats what you want since you dont want to go with the 3.4 Whipple or 2.8 Kenne dont go with hellions, or HP TT or any pre manufactured twin turbo kit that has been made for the Cobras or Machs.

First off all those kits dont go smaller than twin 57s and if you have watched any of the videos of these kits every single one has stupid lag and they dont come on full boost until 4700 to 5000 RPMs in which if you dont have cams you not going to go over 6,500 and that means you made full power for amazing 1500 RPMs by which you just lost your race by at least 10 cars lol.
Here are 5 videos of exactly what Iam talking about

Things are better if you have an automatic but I dont think you do.
And here is how you can keep your Shaker with the Saleen Superchager kit for the 05 but you can run it on your year

I will tell you to look into a pair of GT37 and GT40rs these with the right setup you would be able to be at full boost tops at 3600 to 3800 rpm and that shit will be fast.

My plans: The cams will be upgraded before hand but they're not my concern for the time being as this is for planning purposes. As for what I'm looking for, a high to mid 11 sec street car would fit me great with a some room to grow with experience (eventually Mid-Low 10's).

Reasons for trying to avoid the roots type charger. This car will be daily driven, making it more practical, for fuel consumption, to run turbos or centi-charger (Centri- ist the best option in my case due to CR) as I will be able to keep it out of boost in these conditions. Also the n/a feel created by the roots , as desirable as it sounds, would again make it difficult in city conditions. I'm am aware of lower boost options. Whipple is not an option for me.I don't want to swap intake and last time I checked it wasn't an option for Mach1's unless this swap was made.

Centrifugal Chargers: More efficient than Roots type, so I don't see why you call them inefficient. Procharger in particular run's a 3 core air-to-air intercooler. Kennebell runs the same intercooler as the 03/04 cobras from what I'm aware.

I truthfully don't see a problem with Hellion or HPP or the point your trying to show me. Forgive my ignorance. As for the videos, they don't seem to be doing the drivers or your point much justice.

(Pull Videos) They seem to be pulling decently well .

(Roll Races)What boost are the car's running?Why are the mod's lists so vague in description. For all I know the TT is running 8lbs while the KB is running 14.

(Drag Videos)Are they even launching in boost? Didn't sound like it for the one video we could hear. If it was wouldn't it sound something like this?.....

YouTube- FastMark's 03 Cobra 9.2@155 Hellion 88mm turbo

These videos I feel are a great demonstration of a perfect launch in boost.

You also seem to be making the point the bigger the Turbo the more lag will be present.... however this statement is true a larger turbo(s) will have the ability to produce more boost and are more efficient. To add who had to say that Both turbos needed to be the same size?I could go with one 50mm and one 76mm. Hellion & HPP seem to be well known and good companies. Also the turbos of today seem to have reduced the dreaded lag period pretty well....

[Cricket]

Only issue I have with HPP is the placement of the turbos. You may run into scaveging issues with the oil with them...and that is with the pump.

Hellion would be my preference this far.

That and their customer service is questionable.

[Techniq]

Thanks for the heads up.

[GTermi]

Yeah, dont buy anything from HPP. They love to screw over their customers pretty bad. I trusted Manny to do me right and boy he bent me over and rapped me. They are a very crooked company IMO

[GTermi]

Also, when i went up to HPP, one of their "badest cars(Mach 1)" with that turbo only made 550..for a twin turbo kit u better be making much more than 550 to the tire.
