ThunderCharger Super Charged Apex takes second at West Yellowstone drag races

O.K. the other supercharger co. uses a centri***al supercharger that is basically a small belt driven turbo charger. We use a positive displacement supercharger (or Roots style blower) that makes 1.2 L/rev. We also use a by-pass valve that eliminates blower surge and makes for better drive ability and fuel mileage. We use a liquid to air inter cooler instead of a air to air cooler. Our throttle response is the best of all boosted systems. And with all due respect it's not bragging its more vindication. We have been under the shadow of the other supercharger company for a long time now, and just because they can't run with the big dogs supposedly we cant run with them either. Sorry if I sound like I'm gloating, but we have put a lot of r&d into this project and we are proud of what we have accomplished. :beer;:beer;:beer;


I guess you cant use f u g ???

I appreciate the response and the technical info.

You dont need to explain yourself to us. Just looking for info...not justification.

thanks again, let us know when you have a product for market.

Hay I am happy for you I have been watching you guys for a bit and I have a lot of resect for a company that does not R&D on their customer..(Unlike other people) But I hope you dont forget there are some of us that have had the 300 plus hp and have spent the big money and have figured out what we realy want is 50-75 more hp than stock that is reliable I realy just want to put gas in my sled and 1 belt a year and change and check the oil and thats it I dont want to tune when I go to MCCall and come back home or when I am in reve and then go to Jackson
 
Basically, what we are are trying to build is a supercharger system that will run from 5#'s to 25#'s depending on what your riding style is. Bigger blower turn it slower. We are turning up the wick because we want to know what we can do. You don't have to run it this hard if you don't want to. We were at 18#'s at West. :D:D:D Oh by the way ....this is a STOCK ENGINE. NO MODS. 110 gas. I know that most of the riders want 6-10#'s boost with little or no maintenance so we are pushing it twice that much to see what it will do.:beer;:beer;:beer;
 
I too am very interested in their SC, would like to know when it will be available, before I go somewhere else. I've tried e mailing thunder racing engins twice and it always comes back undeliverable. It sounds awesome and I like the pics previously posted here. would love to see some available product.. Keep us posted!
 
Thanks Dave, that means a lot coming from you. And Lucky, I'm not satisfied with the engine management yet. That's why I was glad to see Dave from Powderlites at the races. He has the best thing going for engine management right now. It's more like what we use for super tuning our blown injected racing engines. It has real fuel and spark mapping capabilities that will interface with a lap top. You can change fuel & spark in each cell that are rpm & load based. Very Nice. His turbo Nytro was the smoothest running boosted sled I have been on. Bottom line is, when we meet on the mountain or trail or lake, I want you to slap me on the back and tell me how much you like your ThunderCharger supercharger and not want to punch me in the nose because you spent a grip of money on something that doesn't do what I said it will do. :beer;:beer;:beer;

Glad to see more products coming out for us sledders. as for the fuel management system that you say dave has, isnt that the same system that Mitch from Synergy helped develope, as well as Blair parker? It seems like Dave is taking credit for this system and as far as I know, Mitch was one of the first people to make it work on a boosted sled?(other than The fella that sells the boxes of course)
just my 2 cents

mitch was the first to use it on a sled just dave is making them avalible for all efi sleds dont think he was taking credit for it just letting people know he has them for his kit & sleds.
 
Nope, it was the full bodied red one. The blue one with the 2 nitrous bottles on the tunnel was our RX-1. It should have been faster than the Apex but we found out after that the primary clutch weights were stuck. It never shifted up. Launched like a rocket ship though. It was blown and had a 100 hp hit of spray on it with a progressive controller. Live and learn I guess.:o
 
Cheers Thundercharger!! I hope one day you make up here so I could take that hot rod for a little rip!:beer; congrats
 
We must have raced your Blue RX-1. Wish we would have had something to squirt. We lost out to the winner in semi's.

Yep that was me. Your sled was very fast also. MCX right? But that ti chassis turbo RX was light. Yours looked like a stock bodied Nytro. I think.?? The weekend was fun and I got to meet alot of good people and even got to ride Dave from Powderlite's Turbo Nytro. That thing was a Blast to ride. Hopefully we can all meet up next year and do it again. I just wish Freak could have had his engine back together. Not that we could have beat him. But he is still the yard stick to measure to at West. ;)
 
Finally !!! You paid your dues and earned that one Bill.

Good experiences riding or racing are all about ... Setup & State-Of-Tune

I run a MPI Stage-I Supercharger (C15-60 compressor) with 50-shot of nitrous ... It makes about 260hp at my elevation ... I'm not worried about losing a dragrace or hillclimb to any other 260hp stock chassis Apex whether it be a turbo or screwcharger ... why? ... because I know it's properly setup and running at its maximum potential ... It has already proven itself on-the-snow ... If I had the larger compressor the results would be the same ... I'd just be making a lot more horsepower.

The most common MPI supercharger kit has the C15-60 compressor which is maxed out at 311 CFM ... There are two even larger compressors in the C30 family ... The Rotrex C30-74 (500 CFM) compressor (equivalent to the 28-series turbo) and the C30-84 (572 CFM) ... The largest of the family C30-94 will support 654 CFM ... It takes about 12hp to drive the smaller C15-60 compressors (C15 family weight is 6lbs) and about 24hp at maximum compressor rpm to drive the larger compressors (C30 family weight is 11lbs) ... The parasitic draw rises linearly with rpm so the hp draw is very low at lower rpms ... An equivalent hp rated Lysholm or Roots type for instance would draw 42hp according to their manufactures literature ... So there is some real hp potential with the Rotrex superchargers >>> IF <<< the larger supercharger systems are properly developed.

Superchargers are not for everyone ... The overwhelming majority of snowmobilers run the big Mits and Garrett turbo's ... but ... there are a few people out there (like me for instance) that don't want to deal with the things necessary to install and operate a turbo or supercharger at a continous 300+hp for which the smaller Stage-I superchargers are perfect ... I just wanted a basic bolt-on performance enhancer leaving everything else 100% stock (especially the engine and exhaust) ... My sleds power delivery could not be any smoother (it's basically a box stock Apex on steroids) ... It makes 1-lb boost at 2000rpm, 2-lbs at 3000rpm, and so on, up to 10-lbs boost at 11,0000rpm ... If I had the larger Rotrex compressor it would be the same, just at higher boost levels, like 2-lbs at 2000rpm, 4-lbs at 3000, and so on, up to 20-lbs at 11,000rpm ... It would have the same completely linear power delivery inherent in the Rotrex type supercharger ... My sleds on-off-on throttle response boondocking at low rpm (clutching, fueling, and controlling airflow are the key factors) is as quick or quicker than the stock Apex ... If I smack the flipper to the bar it pulls hard from a stop all the way out the top (cluching is the key factor) ... The power delivery is completely linear from idle to the rev-limiter ... Like I said at the begining ... Good or Bad experiences point back to Setup & State-Of-Tune
