Hi I have got the chance to get hold of an Eaton htv 1320 supercharger, I know they are the next generation of superchargers and are a lot more efficent they are used on the lotus evora and are used on 4.2 audi as an upgrade. Does anyone here have any experience with them I may get it anyway I plan on building a custom intercooler for it.

Thanks Carl

Which engine are you using it on..? The R1320 is undersized for most V6's, much like the M90 was. Furthermore, the TVS blowers are expensive and inaudible. Eaton has been advertising that they're more efficient than some turbo's, which is true for the compressor, but they forget to mention that the efficiency goes out the window with the belt drive. They are after all still only roots blowers.

Several have tried using the R1900 in the 3800 community. It was a big deal two years ago. Since then the engines and their owners have sort of fallen into obscurity, much like the MP112 crowd. Compared to the turbo cars, they were significantly more hassle to set up, and the owners were broke afterwards. Go turbo..

Here's two pictures I saved in late '09, they aren't mine:




If after reading this you're still entertaining the idea, the compressor maps and specifications can be found at Eaton's website. Here's a link to the 1320 model compressor map and data sheet.

It isn't a wise decision.

Thanks for the response I should have stated this would be fitted to the 3800 engine if it was worth it. Not saying you could get as much as this set up but could be different. http://www.goapr.com/products/stage3_b7_rs4.html

There is a guy on ClubGP right now who has one on his car. The thread is very lengthy and there is a lot of people bashing the guy since they feel he won't see any major HP gains. He's going to the dyno this Thursday to see what his new numbers are with this installed. There is a video somewhere in the thread, not sure what page. Here is the link, enjoy:

You're about to blow a lot of cash for nothing. The Buick V6 is not a 415 bhp, dual overhead cam, high compression, small displacement V8. You shouldn't at all be impressed with the APR Audi. They used a 420hp engine and made 170hp more using an undersized blower. That's a 40% increase in power. Now back to the iron slug 3800, which makes 205 hp naturally aspirated. To get to 420hp, you'd need to increase power by 104%. To romp the Audi you'll need a 189% increase in power. People do this all this time with the 3800, but the little 1320 is not the tool they're using, its too small, and just a roots supercharger.

TVS R1320 - 1.32 liters of air displacement - Very efficient
M90 Gen V - 1.5 liters of air displacement - Moderately efficient

A toss up between size and efficiency. Both blowers are going to be very similar in performance. The TVS blower is inaudible though, so all you'll hear is the 3800 exhaust note. If you use the NA block, top swap it, cam it, buy the expensive TVS, adapt it, intercool it, spray it, and spend twice as long to tune it, you might pull 400whp out of a 3800 like the M90 guys are doing. You might as well be buying an M90 ($400). Go turbo..

There are more people laughing at him than bashing him. He's a dreamer.

He's wasting his time and money, and everyone knows it. If OP wants to be different, turbo the 3800, and paint the engine a different color.

This is all I wanted to know I havent bought it I only have a gen 3 supercharger at the moment but will now probably end up going with a holset hx55 that I can get hold of.

Thanks

I also looked at blowers but after seeing it was costing the engine like 50 to 60 HP to run compared to a turbo at the same boost

I agree for the most part. I don't know nearly as much as you when it comes to the differences between the superchargers, so thats why I'm waiting to see his results. There are a lot of credible experts who have explained why and how this is going to be a waste of his money though.

But I do agree with you, turbo is the way to go to be different, and its the best way for him to make the HP he wants.
