Do head gaskets need to be done when putting a supercharger on? I've got an '02 GT, pretty much stock except for a CAI and exhaust. It's a centrifugal that I'm looking at; I wouldn't be running more than 8 (at max, probably go with 6 or 7). Gonna switch over to 3.73 gears (I have 18" wheels).

Two questions:
I read that my stock compression is 9.0:1. Do I need to lower the commpression for the supercharger?

Do I have to change the head gaskets for a supercharger?

I've been reading around as much as I can and I haven't seen that I need to do the head gaskets unless I have high mileage (which I don't). As far as the compression, I read on a sticky somewhere that 8.0:1 is "optimum", but I don't think I need that.

Help please thank youuuuuu

you should be fine with 9:1 compression, its not too high for boost, its just the lower your compression, the higher PSI you can push. I would worry about the internals first because you can't safely push more than 450 to the wheels on stock internals meaning lowing your compression and upping the boost won't do much when your limit is 450ish.

Yeah everywhere I look it says 400 is the max. I don't know what I'd be putting out with the Supercharger, but I'm not looking to make any kind of crazy power. I just want something under my hood. If later on I feel the Need for Speed, I'll do it then. Right now bills are keeping things a little tight but I have the opportunity to get a whole S/C kit for a real good price.

Most kits only run 8-10psi on stock tune setting so it is all good to go....If the kit really is complete!

Okay so compression is good.

What about head gaskets? I was researching all night and found nothing that said I needed new head gaskets unless the car has high mileage, which mine doesn't. Two previous owners before me, and the car was babied (and still is).

 

[TBapp3]

No need as far as I know!

You should not need new head gaskets at all by any means. What type of kit are you looking into?? and are you going intercooled or non-intercooled?

 

[TBapp3]

^+1 what kit is it!?!!??

No need to change your head gaskets. Two years ago I ran 12 psi on my 9 to 1 306 with cheap graphite head gaskets. Last year I was running 9-12 psi on my 9.4 to 1 363 with the same kind of graphite head gaskets. So I think you should be fine, your head gaskets will last if you have a good tune and dont run it lean.

I have 8.5 to 1 compression and wish it was 9 to1 so I could get a bit more power. 8 to 1 is a little low in my opinion but your setup will be fine with 8-10 pounds of boost and a good tune. It will toss your head back.

It's a P600B pro-charger. Yes it's intercooled, and it comes with everything I need. I've been checking up on anything and everything I would need to know, and I think I'm going to go for it. It's a steal at the price he's asking, and it's totally in my budget right now.

I'm excited!! lol And thanks for all your help, guys, seriously.

Make sure you upgrade the fuel system to more than you need for now cuz once you get hooked to the boost, more boost is just a pulley away.

It's got fuel injectors and a fuel pump, I asked about fuel rails and the guy told me that I could use the stock ones, but I'm thinking about getting an aftermarket set anyway.

Awesome


Everybody wants to be blown!

You dont need to touch your engine, gaskets ect. With that compression you will be safe to at least 10psi of boost. My car ran perfect with 10.1 and 12+ pounds of boost and most important a gooood tune.

 

[GTStatus]

I read that I can run up to 8 pounds really safely, but I'm new to the whole forced induction thing so I'll probably start out low around 6psi at first until I get used to it. My boyfriend's car is turbocharged, and feeling the power in the passenger seat is crazy; I can only imagine it from the driver's seat!

Sounds like its gunna be awesome when the supercharger is on there.

yess the supercharger power is great...i'd just go 8lbs of boost right off the start tho. I'm running 10lbs on a conserv. tune and yah the 1st time u take it out you have to feel the car out all over again but it wont be anything u cant handle...i would upgrade to atleast a nitto 555R drag radial tho* so glad i did that be-4 i put the KB on my car bc theres no way your going to hook in 1st gear with a summer tire. but just my . goodluck!

 

[GTStatus]

Yeah, the kit came with an 8lb and a 12lb pulley. I'm definitely going 8lbs first. Like I said, I've never driven anything with forced induction. I found some awesome gauges though, can't wait to get those! And my gears arrived today - yay!

you getting 3.73's?
