Building a Bigger & Better Roe Supercharger system

[BOTTLEFED]

Ok, this should probably go in the tech section, but I wanted to get as much feedback as possible on this topic.

I want some opinions on fitting a larger Kenne Bell supercharger unit to a Gen2.
I'm thinking the 2.6/2.8 Big Bore twin-screw could be modified to fit. Maybe a new manifold would need to be made. Maybe modifying the hood would be necessary. Maybe an intercooler could be added.
This will not be a simple swap, but can it be done and would add a whole other level of power to the Roe setup.

Ideas and suggestions welcome.
I'd like to get some more technical/logistical info on doing this as well if anyone has some.

The hood would be the biggest issue I would think. If you didn't mind a 4" cowl, I think you could get a larger unit, maybe 3.3?, under the hood with great results. I would love to see a GTS with an old 671 sticking through the hood!!

call sean before you do anything. i know he said he tried doing it but had some issues. heat was the main issue i think

Can you say "Sawzall" ?

I 'thought' there were 2.6L / 2.8L versions that just used a longer housing, but were not necessarily taller. Lots of room to go horizontally if you put on a shorter snout. Can't seem to google any useful info at the moment through.

Years ago, there was a company that had pictures of a huge roots type blower on a Viper engine. Not sure what happened to them. Always thought it would be a blast to show up at the next VOI with a 14-71 sticking through the hood.

While I wouldn't trash a stock Viper hood for that, I'd gladly saw a hole in an aftermaket hood to make room for a blower. It would look so badass.

IF you end up using a different manifold, try to get better air distribution to the cylinders (especially 9 and 10).

Good luck, I'd love to see someone do a larger compressor.

GREAT!!! Then run a chrome trim ring around the opening!!!

one of the pluses about creating a new setup is being able to add an intercooler and thus solving the Roe's heat issues

something like this for a manifold/IC combo

That's it! Have to take measurements to be sure, but I don't think it will fit without a hole in the hood Actually from the looks of it, the entire SC and part of the intake manifold would be sticking out.

Speaking of clearance, the Diamondback hood gives about 2" more vertical clearance to work with.

yeah baby

Would be interesting... I wonder if all the money and effort for something like this would benefit, or would it be best to just go with some turbos that you know will put down the power.

IIRC, 1badGTS knows a guy who did an intercooler for his rowe recently, ask him about it. i think the guy had the work done here in NJ. if the guy has parts around or the rowe car, id go snap some pics of it for ya. let me know

 

[treesnake]

My Roe has been ported, has a 12# pulley with a Weaver overdrive crank pulley, (14# boost) water ****, CO2..... Everything possible....Runs good

But,... after driving a Turbo. All the time spent on the S/c was almost a waste of money. There is no comparison.
The TT's a regular car until 3000RPMs.. then spools up to over 1000 HP....
On pump gas and Air conditioning....

Dollar for dollar, if you want big power and efficient high performance... Turbo charging is the only way to go....PERIOD.

IMO... from personal experience ...

And more important, from personal time and expense with both....

 

[whitebluevipe]

that looks like one of the don hampton superchargers.

I'm not sure if I really him. He doesn't seem like the most honest guy. If he wants to come on here and prove me wrong, that would be great.
Thanks for the offer though Phil

BINGO, we have a winner! You get a gold star

I understand completely. I rode in a TT car and it was crazy. However, the power seems a little useless on the street. It all comes on at once and is almost uncontrollable.

You say it would be cheaper, but if we can find a way to upgrade the Roe setup, or design something new, it wouldn't cost much more than a new Roe kit. You can't buy a reliable TT kit for less than twice the price of a Roe kit, and the Roe kit is way easier to install for the DIY guy than turbos.
I appreciate all the hard work you have put into your setup. It looks like you are doing everything imaginable to get as much power out of the current Roe kit as possible. I can't wait to see how it does and what #s you finally put down.
But just think, if we can come up with a system that takes care of many of the faults of the Roe kit, then we can run more boost, and an IC, and be more efficient.

In my mind, an upgraded Roe S/C will be in the 800-1000rwhp range (and who knows how much tq ), but it will be reliable and easy to work on. It will be a little more difficult as a DIY project than the current kit, with a little more fab work and cutting - perhaps like the Paxton. It will certainly cost more than the current Roe kit. It may require modifying the stock hood, or the optional purchase of custom hood. It may also require an AEM or SCT to tune it. The fuel system will obviously need upgraded as well. It won't be for everyone, and I think there will still be a market for the original Roe S/C kit.

You are probably correct. The Roe type set up is more DIY..

The problems start with the "might as wells"...
For example... since your already changing intakes, might as well do the heads. If your pulling the heads, might as well change pistons......
That's how it starts......

I remember a couple years ago there was a thread about a company that was testing a larger "roots" blower on a Viper. I did a search but can't find it. I thought I saved it. I will check my computer at home.

Anybody remember that thread?

 

[VIPER BAZ UK]

Speak to Sean......... ;O)

 

[KNG SNKE]

Watching this thread. Thought that supercharger setup would be phenomenal I would not destroy a hood to install it.

 

[Burntrubber]

i think you can raise up the rear brackets for the hood about an inch. might give you enough room to put on a 3.3 that is used in the viper trucks. probably an easy swap and if you can run 12# boost you could probably put down over 750 on pump gas.

The hood would look ridiculous with a 1 inch lift in the back.

 

[BOTTLEFED]

I think the best solution would be an aftermarket hood like the diamondback

 

[1BADGTS]

Nick at MODERN PERF (732)222-3679 has a custom intercooler which flows gallons of coolant =Dramatically lowers inlet air temp over the water injection set up.(he will custom build you one to fit under the stock hood.It isnt cheap but works well in race applications )

 

[KNG SNKE]

Got photos?

 

[1BADGTS]

Got photos?

Give Nick a call and he will e-Mail you some .As i posted earlyier its NOT CHEAP (PHIL C-Jackson NJ )has one (does a ton of roadracing in hot weather )works very well .

 

[KNG SNKE]

Ok to me not cheap is a grand, how not cheap are we talking .

 

[MichaelP]

The way it sounds it is probably more like 5K for the cooler
