IA Forced Induction Friday Sale!

[Rodger]

I checked out their website (which I'm surprised they didn't link to here). It's good they use resized injectors and a reflashed DME map. Anyone know what the life expectancy of the supercharger is? I recall a centrifugal kit made for Honda Civics that only lasted about 50,000 miles before it would need new bearings.

Also, any idea what the intake charge temperatures are?

Thats awsome it would make a great project and Im going to look into it. No, I dont worry about my car blowing up. There are some on this site that have non-superchared guys afraid to even drive thier cars. Some are even selling thier sweet rides because they are afraid of what might happen, please. Im always trying to think about how to keep the oil and water cooler, great info thanks.
Schnell,
I dont remember the Honda kit but the roots type like on my car is the same one used on several different factory models. Its an M-62 Eaton which is supposed to have the oil changed every 30k miles and the bearing rebuild kit is like 100 bucks or so. Im not thinking that I will even have to rebuild mine. I think the Boxster wont have a detonation problem until it goes over 7-8 psi. I read the air intake temp charge somewhere but I cant remember what the number was. I sat in traffic last night for over 45 minutes at idle on the x-way and didnt have any problems. I do run a little hotter than it used to be. My needle sits about 3/16 of an inch above the 180 mark. I know its not accurate but Im just pointing out that it used to be right on 180.

Not just the supercharger but the whole engine. This would be my major concern when considering mods that signifficantly change loads, strains, pressures, and temperatures across the engine. How would these changes affect the engine over time? I don't know enough to judge what's reasonable but I would think factory engines go through a lot of testing before a final design is put into production. It is unreasonable to expect that most after-market shops would even come close to approaching the same testing standards. That's why a crate engine drop always looks more appealing (to me).

I wonder why the Mini S gave up the supercharger for their 07 models in favor of a turbo (no sarcasm meant at all).

Boost is boost, turbos and SC units compress air. Mercedes CL55 has a supercharger, you ever drive one of those, nice. I think the argument is going to be that the turbo was more efficient it made like 8-12 more hp. To each his own, I would'nt think waiting for the turbo to spool up would be a bonus on the Box because the bottom end is dead on our cars. With the SC the boost comes on fast when you nail it.

Ohio, sorry, didn't mean to rain on your parade. You obviously know more about this stuff and are way more handy with these mods that I will ever hope to become. I was just expressing a genuine concern about differences in factory vs after-market testing rigor -- warranted or not. I am convinced that you are happy with your conversion and are enjoying the hell out of your SC Box, and that's all that matters. Happy Thanksgiving!

No offence taken. Have a nice Thanksgiving yourself.

I will chime in here since my Boxster S was IA's first......

Low boost, low temp pProcharger C1, resize injectors GIAC tune and you are set... Stephen Kasper builds great Porsche motors he is not just a "tuner". If he was I would have never gave him my car for over a year to develop this system. He builds SAFE high HP cars and could pull more HP out of my car but said it would be pushing it. In his words “you can not get blood from a turnip.”

I have even went as far as offering my car to anyone to drive that are interested in this system. I did not have to nor am I receiving any funds for this. I believe it is that good. As for a point of reference I had a brief run at the last Seattle drive with a 997TT… Wow was he surprised when I was pulling on him from 60-110 mph…Ask Dacid_J who was in this car and is a member on this board when I pulled on a modded 3.4 996 that smoked his 01 Boxster SI was amazed and so was the Bob who wrote the article for Excellence Mag that will be out in the next few months. It is that good


BTW: IA and many others have installed the EVO S/C on over 100 on 996's (they have a higher compression then Boxsters) and not 1 has went boom. The bigest issue that they had with that kit was changing from a .02 boost hose clamp to a stronger one

Hey blink, I dont think an oil cooler would help much without an s bumper, or some other 3 hole variation.
