RedM Posted April 25, 2006 Share Posted April 25, 2006 Is there or has there ever been a supercharged only Supra? Seems like a good charger would give power straight away and so would be pretty handy. What's the highest BHP you could take a Supra to with a SC? Any ideas of cost? Would going from TT to SC be a step backward or a more sensible option than going for a single? Thank you Link to comment Share on other sites More sharing options...
ChrisSZ Posted April 25, 2006 Share Posted April 25, 2006 ...........or would it be the perfect in-between for N/A - T ?? Link to comment Share on other sites More sharing options...
Tom S Posted April 25, 2006 Share Posted April 25, 2006 hence why I am going NA-T Link to comment Share on other sites More sharing options...
Bob Posted April 25, 2006 Share Posted April 25, 2006 Rotrex do the C38-81 which is supposedly good for 400-630bhp tech sheet thingy here: http://www.rotrex.com/pdfs/Rotrex_Technical_Datasheet_C38_Range_V1.4.pdf Link to comment Share on other sites More sharing options...
Daston Posted April 25, 2006 Share Posted April 25, 2006 Aparently this is a very common thing to do in the Lexus world there is one guy on the NA-T club forums who also has had this done. Link to comment Share on other sites More sharing options...
Lucifer Posted April 25, 2006 Share Posted April 25, 2006 Jagman is doing this, and yes it has been done before. Link to comment Share on other sites More sharing options...
Digsy Posted April 25, 2006 Share Posted April 25, 2006 Would you not have to push a disproportionate amount of power through the engine to get the same HP at the flywheel as you do for a big single? I did some rough calcs based on Ian C's 626BHP dyno run and estimated that it was taking some 71hp to drive the compressor. On a turbo that comes from the exhaust. With a supercharger it has to come from the engine itself, so an equivalent SC engine would actually be producing 697BHP once you take the addiional parasitic loss into account. Of course, the peak torque would be a tad lower down the rev range Link to comment Share on other sites More sharing options...
Lucifer Posted April 25, 2006 Share Posted April 25, 2006 Unles syou were using a small charger to spool the turbo? Link to comment Share on other sites More sharing options...
Digsy Posted April 25, 2006 Share Posted April 25, 2006 Well, yeah, but the original question was has anyone done pressure charging using only a supercharger, and what kind of powerr could you take it to? Link to comment Share on other sites More sharing options...
b_have Posted April 25, 2006 Share Posted April 25, 2006 Did Arnout ever get the dual pumps working together? Link to comment Share on other sites More sharing options...
Daston Posted April 25, 2006 Share Posted April 25, 2006 I think a "Supra charger" would be better suited to roads where you need low down power/acceliration and not 100+ speeds Link to comment Share on other sites More sharing options...
Sharpie Posted April 25, 2006 Share Posted April 25, 2006 Jagman is doing this Is he not adding a SC in addition to the Turbo's though ? i.e. running both on the same car ? Do you know how he is getting on with this ? Link to comment Share on other sites More sharing options...
RedM Posted April 25, 2006 Author Share Posted April 25, 2006 So, you could have a Supra that was comparable to a sensible single but with no lag? Money? Link to comment Share on other sites More sharing options...
carl0s Posted April 25, 2006 Share Posted April 25, 2006 I was thinking about this again last week.. funny that. Twin charging would be the ideal, but I'd like to have more off the line power, and would be interested in seeing some SC projects.. Link to comment Share on other sites More sharing options...
Guest blueangel Posted April 25, 2006 Share Posted April 25, 2006 This is what i am looking into for my na but as of yet i havent really looked into it yet as i want the car on the road first then i will look into it more seriously. The idea for me is to have something a lil diff rather than more power. Link to comment Share on other sites More sharing options...
ChrisSZ Posted April 26, 2006 Share Posted April 26, 2006 I'd love to go SC rather than NA-T - it would suite my driving style more since I don't do a lot of high speed motorway driving, buch more A and B road blatts ) Anyone have any idea on prices for this?? Would it work out similar to a turbo conversion (price wise)? Link to comment Share on other sites More sharing options...
Ian W Posted April 26, 2006 Share Posted April 26, 2006 i thought the only superchargers done had been added to TT's or VVTI n/a's. doesn't the dizzy cap get in the way or something so you have to switch over to coil packs? Link to comment Share on other sites More sharing options...
Gazboy Posted April 26, 2006 Share Posted April 26, 2006 So for a car that struggles with grip off the line, you want to supercharge it? I've always fancied a LS6 twin turbo conversion.... Link to comment Share on other sites More sharing options...
carl0s Posted April 26, 2006 Share Posted April 26, 2006 So for a car that struggles with grip off the line, you want to supercharge it? Mine doesn't struggle for grip. I have to powerbrake to spin the rears. It is a UK auto though. Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 26, 2006 Share Posted April 26, 2006 BMEP on old style supercharger installations was very poor, you'd have to look at a clutchable SC like on the AMG SL55 Merc, or some other new generation supercharged engines. Chargecooling would be needed too, and a workable turbo installation will, as a result, be a lot cheaper and easier to arrange than an equivalent efficiency SC installation.

carl0s Posted April 26, 2006 Share Posted April 26, 2006 So does this mean we can't somehow fabricate lots of pipes and fit on one of the superchargers from a new BMW Mini-Cooper S? (They are easily found on eBay from new cars).. Link to comment Share on other sites More sharing options...
