Darren Posted February 2, 2003 Share Posted February 2, 2003 Is 500 bhp (UK measurement:p) attainable on hybrid turbos? Thats the figure in my head I want for my car and I like the current turbo config so whats the score? Thanks in advance. Darren Quote Link to comment Share on other sites More sharing options...

adi Posted February 2, 2003 Share Posted February 2, 2003 Depends on the build.. i've got turb tech hybrids and supposedly they are good for 550 at the crank.. others may be less, may be more. Quote Link to comment Share on other sites More sharing options...
Alex Posted February 2, 2003 Share Posted February 2, 2003 Its heat that is the enemy of Hybrid systems. Keeping the EGT's down with the restrictive manifold is a hard task. But to get a better manifold is cost prohibitive. Quote Link to comment Share on other sites More sharing options...
Syed Shah Posted February 2, 2003 Share Posted February 2, 2003 Some really good hybrids with a custom manifold, and you could well get 500HP at the wheels! Depends how far you want to go with them. If you really want a lot of power, then perhaps a small single turbo (SP59?) with suit the job better, rather than extracting as much as possible out of hybrids.

Guest Terry S Posted February 3, 2003 Share Posted February 3, 2003 Can't see you getting 500 WHEEL bhp Syed. Thats almost 600 flywheel. Yes 500bhp *flywheel* is more than possible, but the manifold is a big restriction. I actually melted a GReddy EGT probe! Speak to Leon.

Darren Posted February 9, 2003 Author Share Posted February 9, 2003 Matt, Need to find some that are known quantities...There seem to be hybrids and hybrids. I think hybrids etc are a bit of an investment and you need to get some tried and tested ones...Any ideas mate I think you are in the same boat as me?? ie thinking bout the next step........

Chris Wilson Posted February 9, 2003 Share Posted February 9, 2003 With the VVti you might be better running the stock ones to the limit and concentrating on charge cooling to the max. You should be able to get 480 out of the stock ones, I doubt you'd safely get 500 though, especially on pump fuel. Quote Link to comment Share on other sites More sharing options...

I'm running at 1.2bar at the moment on the turbos what are you suggesting we go to. Thanks this is interesting. Darren Quote Link to comment Share on other sites More sharing options...

Lottery win = one of those in the garage It's a Lola 92 / 10 sports GT racer with a Judd V10 F1 engine. Sort of a favourite of mine, but very expensive Quote Link to comment Share on other sites More sharing options...
Adam W Posted February 9, 2003 Share Posted February 9, 2003 So what do you have to do to an F1 engine to make it reliable enough for 6/12/24-hour GT racing? Just reduce the rev limit or is it more involved than that? It'll look nicer once it's been painted . . . Quote Link to comment Share on other sites More sharing options...
Alex Posted February 9, 2003 Share Posted February 9, 2003 Darren, He means cool the air coming into the engine as much as possible. IE FMIC - not necessarily an off the shelf one Water Injection Cold Feed Airbox Chris, Have you got a new toy yet?? Or are you waiting till the season starts in ernest? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 9, 2003 Share Posted February 9, 2003 The Judd V10 in the Lola, for example, will run tamer cams, so won't rev as high, probably less compression, too. It's the revs that kill F1 engines longevity. It will also be bigger in capacity, probably a 4 litre, by boring / stroking. Look better after painting... ? You must be joking, I want a snow white one, and ONLY a snow white one Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted February 9, 2003 Share Posted February 9, 2003 Alex: No, no new toy. Getting withdrawal symptoms now, need a speed fix urgently It's nice having a wodge of money in the bank, but I'd rather have another toy Was hoping to have found something interesting that wouldn't depreciate too much by now, but it ain't happened yet.

Very complex and not successful. The heat needed to be removed far exceeds the capacity of any sensibly sized A/c refrigeration plant for a cars underbonnet space and engine loadings. No good having a potential 40 HP gain from charge refrigeration if driving the `fridge uses 55 HP Quote Link to comment Share on other sites More sharing options...

I'm running at 1.2bar at the moment on the turbos what are you suggesting we go to. Thanks this is interesting. Darren What i was meaning was the added complexity of running the VVti from an aftermarket ECU, and mapping the VVti stuff might make it more economic to keep stock turbos and ECU, run them as hard as safe, and concentrate on dropping chrage temps, but acepting you might not get to the 500 BHP figure safely. I still think any turbo upgrade, be it to single, twin parallels, or a hybrid sequential pairing needs an aftermarket ECU to bring out the true potential. Being VVti means added complexity and expense. Quote Link to comment Share on other sites More sharing options...
