Ill try and call Brenspeed tomorrow + shoot them an e-mail to let them know I want to upgrade to the intercooled version

Can't I just keep the boost turned down so that there is less chance of grenading the engine?

If I keep the car garaged will I have to worry about running the car in cold temps? I am in Kansas and it does sometimes dip below 20-25 degrees, it has especially been like that this year.

I had gears before on my old 06 GT Convertible and I didn't really like them. I might do them later after the SC is on.

20-25 isn't bad.. its when it gets into the negatives where it does damage (don't feel bad, other shiet gets effected at that temp as well lol)

You can always run lower boost with most kits, it's no big deal. Just make sure the tune is spot on, and use premium gas.

Enjoy!

PS

get some delete plates while you're at it, or a high flow manifold if you can swing it.. it's good for about 20whp or so.

What gears did you have on your 06? the 4:10s make a hell of a difference in my auto w/vortech.

I went with 3.73's on the old car. I think the reason I didn't like them was because I hadn't figured out the launch yet.

lol trust me.. I hate the 4.10s when I first got them as well.

It takes awhile to figure out how to launch properly. Once I did, I was hitting 2.0 60 ft.s all day at the track on street tires. I'd imagine I could drop it to 1.8 or lower on ET drags or even 1.5-1.6s on slicks

The 4.10s are great, but be very aware that the gears are literally 1k from one another, and it's either all out (WOT/downshift) or nothing at all because it'll constantly up-shift to a higher gear for you (in traffic).

Your highway RPMs will also go up (2800@75mph).

With the 05's-09's, the stock 3:55's are fine with a twin screw. You'll simply spin your wheels with shorter gears unless you're on Drag Radials all the time.

With my 06 weighing around 3500 now after some weight loss, with my Saleen @10lbs now @454rwhp, 442trk, I am faster off the line than a GT500 still because of my lighter car, longer gears and 5 speed manual rather than six. The GT500 with 3:37 gears and six speed manual spins the wheels on launches easier than my car.

For my cars weight, and driving on the street 98% of the time, I prefer at my present HP and torque on a twin screw not to have shorter gears and a six throw. Racing would be a different matter. Erik

I had 3.31s on my 09 when the Vortech non-IC went on. I was still a tire spin show, they'd light up at 30mph... I upgraded to 3.73s and never liked them. They just didn't seem to make much of a difference to me.

Like mentioned earlier, if they won't switch out, a good meth injection system will also do the trick.

My 08 (roots blower) is intercooled & my 1990 (centri) has a meth kit on it.

I am kind of worried about the whole starting the car in winter thing. I have been reading a lot of different threads on that issue and can't really seem to get a straight answer.

The general consensus of what I found was that the car should be fine trough the winter but it's a really bad idea to start if it gets in the negative temps. I read a few people said they had taken their car through multiple winters with a Vortech, one guy was more specific (Chicago winter) and said they never had any problems, just let the car warm up first.

It doesn't usually go below 20 degrees here, typically it's 25-40 degrees but there are some days where it gets close to zero, but rarely negative.

I was thinking of switching to a 0w30 oil since it flows better in the cold but I also read the issue isn't with the oil flowing, it actually has to do with some parts in the blower that may not function properly at low temperatures which can cause a failure.

I really want to make sure and do everything possible to not grenade the engine.

No fun at all?


Faster than stock sounds fun...And I'd assume he'd still be faster than his current setup...See OP sig

Agreed!

With an Auto, OP, I'd agree that 3.73s may work best, but I've never been in a blown auto...I'll let stealth and Flap tell you, their they experts here...

Sounds super fun for all, except my tire fund...

I'd be scared also...There's a lot that could go wrong, and you seem to be on the border of too cold...I assume it's a DD...As for the oil, I *believe* the throwback is the same as the Vortech in that it's self contained, meaning changing the oil viscosity in your engine oil won't affect the S/C at all...And I'd stay with the wieghted oil the S/C recomends...

I'd say if you can afford it, go intercooled, and if not save up for it...Either way I'd suspect you'd be faster than your curtrent setup, which is fun...That cold alert scares me, and for the $$ of the IC'd version a TS or roots may be better for your application, especially with auto...

Brenspeed called me back this morning & got it upgraded to the intercooled kit.

According to them it should be fine in the weather here as long as you let the car warm up... hopefully that is correct. The only story I read about one blowing up from this was in -40 temps.

Ill definitely be trying to keep the boost down til I have enough cash to comfortably be able to buy a new block. I'm sure I will have to upgrade the wheels, tires, brakes now as well to fully enjoy the car.
