I went to Atco raceway for some of the Pan American racing and Atkins Rotary had just finished their EFI super charger. Here are some pics. I didn't get to talk to him much about it but this is what I gathered. It's a complete bolt on kit, stock ECU,stock injectors, this one was running 6 pounds of boost. Sorry I didn't get more info but there was a bit of a crowd. And all with a million questions. Really cool people BTW.

 

OMG that is bad ***!!!! I'd love to see what kinda numbers it produces

 

I can say that many many people have been waiting for this. Did they run the car on the track at all?

 

Wow. More details would be excellent.

 

Yeah I wanted to talk to the guy more but there where about ten people around the car and all asking basic questions over and over HOW MUCH HP!. The car was just finished before he got there, and had not been on the dyno yet. You can imagine how ruff it must have been saying that a million times that day.

 

it's the same supercharger they've always had, but w/ a replacment extension manifold to incorporate the DC and TB. I saw a picture of it a while back, but didn't think a thing of it... as it's still too expensive when compared to a turbo.

 

I wonder how much it is. I was just about to buy a 7incher and put a carb on it.

 

WOW, i gotta get my hands on that, i can only guess the price, but if it really is BOLT UP, than it may be worth it, on the other hand, there goes the tranny, lol

"I really really want that"

 

time to wait a few months?

 

that 6psi would be preatty strong on a high compressionn motor. Looks like they get rid of the 6 ports. wonder why they are using a stock ECU, why not a t2 one? did it have an SAFC, or anyother piggy backs on it?

 

I called them and talked to them it a few weeks ago. The 7 inch will boost up to 17 psi if you get the right size pulley for it.

This link shows the HP numbers on different motors with a 390cfm carb and 10lbs of boost

My friend Ian is currently doing a supercharger conversion as well. He is a machinest so he is building everything from scratch. He still has yet to build the custom intake manifolds and adapters to hook everything toghether. Also has to extend to reach the alterntor in its new position.

He does not have a computer at the time, but if you have any questions I will be able to get answers from him.

The supercharger is off a 3.8L thunderbird, totally rebuilt.

Has a bunch of work still needing to be completed, but most of it is there to get a good idea. the supercharger is just bolted down by one custom bracket in the pics.

heres the pics

Oh f#%k! That thing is sweet!

Mad props to your friend for the nice work.

 

Damn- I have been hitting Atkin's website EVERY DAY
waiting for this to come out- and as soon as I rebuild my motor (will be a little while) I am getting one of THESE!!!

 

I'm wondering if locating the pump right above the hot exhaust manifold is a good idea? Why not ditch the AC and PS and put it over there?

 

i love the set up they have minus the p/s and a/c bracket and all still being on there but i have one problem with it..
won't that thing just be pushing in a **** load of hot air.. since with that set up you can't install an intercooler between the engine and the S/C and since it sits right on top of the exhaust manifold/headers that things gonna get pretty hot.. how dense is that 17lbs of boost gonna be?

P.S. man i'd really like that with a cleaner engine bay

 

is that car drivable? is it running yet or did they just have it there to show it

 

Mmmmmmm, superchargers.

But seriously, what is the plan for cooling the intake charge with these setups? At least a cold air intake should be on the Atkins setup. Hot engine bay air plus compression, roots heat build-up, and NA c/r rotors could mean detonation without water injection or aftercooling of some sort.

 

yeah but keep in mind, those numbers are for the standard blower, with a CARB. The one he is talking about is an EFI blower. Two different animals.

God I hope they came out with an EFI blower, that would ROCK!!

 

lets all keep our fingers crossed. I know the majority of the NA guys here wanna get blown. haha

 

Any reason it wouldn't work on a First-Gen with a 13B? (GSL-SE) Think this **** will pass smog? However doubtful. Oh well I'll wait for a RENESIS swap =P

 

yes the car is drivable. I heard it run sounded good, somewhat stock sounding with just a little whine from the SC MMMMMM I don't want to give out any misinformation so your best bet is to call them. sorry

 

twin screw SC, least thermally efficent SC thier is ( @ 56%) , with no IC and right next to the exhaust ( as has been pointed out) , I bet that at 72 degrees ambient that thing is pumping in 160 - 180 degree air..

 

I called Atkins, and they will only say that they are still working on a fuel injected kit, and it will be finished soon...
