Intercooler would be my best guess and more like my best hopes.... 
Significant enhancements for Roe Superchargers coming in 2005 ..
- Thread starter Sean Roe
- Start date
Hi Everyone,
Sorry for putting that out there and not responding quicker. I posted on Friday and was ******* this weekend with holiday related activities and helping my stepson buy his first car (for your safety, avoid a blue Geo Prism if seen in the 32259 zip code if a 16 year old male is behind the wheel).
We have a few things coming in 2005, but the first will be a straight forward water / methanol injection kit. We're putting together the production kit now.
Without going into a lot of detail about testing, suffice it to say that it provides a very noticeable improvement in the power and makes the car even more fun to drive. We did all our testing on the runways here, and then went on the dyno to verify the results. On the dyno, our peak numbers went from 667 RWHP to 702, while torque went from 697 to 722. At low RPM’s, the torque gain is very good. We picked up 76 RWTQ and 31 RWHP at 2,200 RPM, which is really easy to feel when driving on the street.
This will allow ALL the people with our blower kits to increase their timing, and / or boost, including the cast piston cars. The people running the lower boost pulleys and 91 octane will probably gain the most benefit, as they can increase the boost to 6.5 and run more timing advance. The additional benefit on the cast piston cars will be keeping the top of the piston cooler, which helps make it more stable and stronger.
Regarding putting fuel injectors on the inlet side of the Supercharger, yes, we did that on a test and it does work very well also. But, not quite as good as the water / methanol at these boost levels. We’re putting 4 injectors on the inlet side of the Gen3 kit.
For the boost levels we’re running, I believe the water / methanol injection is more effective that any intercooler we could package into the kit. Furthermore, it can be done quicker and for less money.
We’ll get everything together and have it ready soon.
Regards,
Sean

HOT D*MN!
H2O and whatever the chemical symbol for methanol to the rescue!
Any guestimates as to when it will be available and cost?
BTW - I still want one.

I like the extra injector idea...
One downside to the water kit is it's one more maintenance item to check. Be curious to see what size reservoir, where it's installed and how long it lasts - and I know that will vary a lot based on driving habit!
But will I pony up some more money for Sean's water injection set-up? That's a 99% yes!

Sean, are those #s using 10# pulley and stock heads?
Thanks

Dang! I don't know if I can hold out much longer. I have been tempted to purchase the Roe Superchager for years but this is getting too good!

Used a water/alcohol injection system on a small turbo car a few years back. I rigged a fluid-level switch in the fluid container which set the bypass valve to open at a lower PSI if the fluid ran out. It also triggered a bright yellow LED on the steering column to let me know I only had 3 PSI of boost. This turned out to be invaluable as I ran out of fluid frequently. Had I not done this, my only indication that I was out of water/alcohol would be very destructive pinging.
I'm sure that Sean will supply something similar and tie it into the VEC-2 and the blower bypass valve... I'll say this much -- you'll end up having much cleaner spark plugs!

Hey Sean,
Be sure to send me pics of that upgrade when you finish it, I wanna try and incorporate it into my scale 1:43 FE Viper GTS if pics show me that it's doable

Good question.

Anybody have a guess on the price?
What's the big difference of this **** kit vs other **** kits you can buy?
Here are the drivetrain specs on the shop 1996 GTS:
93 octane pump gas, standard SC kit with 2.5" pulley yielding 9 psi boost (we call it a 10 lb pulley, but the better the engine flows, the lower the boost), 1.7 roller rockers, our cylinder heads (chambers left larger to reduce compression to approximately 9.1), B&B 1&3/4" headers, high flow cats, B&B cat-back, 70 mm throttle bodies, stock airbox punched to 3" outlet, S&B air filters, aluminum flywheel, stock bottom end - clutch - trans - diff and fuel pump (with voltage booster). Other than the heads, it's a pretty standard set of mods. With stock heads, the torque would be the same to slightly higher, but with less high RPM HP.
The tune with the water / methanol was done while driving, then verified on the dyno. The tune and boost pressure were not "to the max" as this was a street test and tune project, where you could get far more aggressive on race gas.
For price, I think we'll probably end up in the $400 area.
To prototype the water / methanol kit, we started with an upgraded kit from Snow Performance. In the end, the difference will be that the kit has been reworked to be Viper specific, with a proper sized reservoir, correct sized nozzles, wiring harness and installation instructions. It will be controlled by the VEC2 and will come with a recommended tuning setup. Basically, we're doing the R&D and leg work to make this an easy install for people who have a Roe Supercharger on their car, so they can get more power and enjoyment out of their mods without spending much.
Also, keep in mind, the post was titled "... enhancements ...". The topic has changed somewhat, only talking about one enhacement, albeit a good one. The other items in the pipeline are geared toward the guys who can't seem to stop wanting more power (you know who you are) and general improvements to the system which should also make more power.
Regards,
Sean
PS, Over the next few months, I plan to set my phone down more and focus soley on testing and development. We have a good staff here to take care of everyone and need to make use of it. I want to get more of the ideas out of my head and onto the road, so I have to make some changes to free up more time for R&D. The best way to reach me for general questions and help will be by e-mail, but I can always be reached by shop or mobile phone if urgent help is needed.

My Roe'd 1:43 GTS needs more power too, lol
