I'm use to NA and nitrous motors so please bear with me if my questions or comments seem "Basic" lol

Long story short..... I built a 402 for my Z28 with expectations of spending time at the track, well I spent all this year with a unforgiving work schedule and no track time. I've decided to part out the Z28 and I recently picked up a 2001 SS that I want to be Fun street car! that will keep all comfort options and get the same power I was use to with the Z28.

Heres where I need to see if my current parts will work well with a procharge build or will I need to change up some things.

402 LS2 10:1 Compression
A.I CNC Ported L92s milled .020"
LS9 Head gaskets

Aster bracket Upgrade
Large Truck hat upgrade
Front mount Intercooler w/race valve
1000cc injectors
AMS 1000hp Custom Fuel System

Mcleod RXT Clutch
QTP Bellhousing
LT1 Radiator
SDCE Dual Fan Kit
Boost Gauge

NGK Wideband

My hp goals are really conserative 500/500 on a Mustang dyno If it makes more great but my main priority is to keep great driveability for everyday use if need be. My second is to keep the A/C, Cruise, Traction control, ABS, and the interior intact. Last but not least is to get back to 500hp on a mustang dyno on 93 octane.

Am I missing anything? Will the FAST 102 hold up to boost? does my compression ratio work with my plans and goals? There are some things that will need to be purchased, some others I'm taking from the Z28.

Dyno Video

 

I would go with our 232/240 595/608 on 115 camshaft. Check out the dyno sheet at the link on my website for that cam, it is a very similar build to yours. Bob

 

I like the build. My compression is 10.3 to 1.
That thing is gonna make 700 or more to the tire.

Take a look at my build.

Bob thanks for the advice I will look into that cam as well.

It was your build and a few others that helped me make the decision to go the Forced induction route. Your car is badass!

 

I like yours cause of some of the better parts you are getting Especially the 1 7/8 headers. Can't wait to see it done.

 

LOL....Thats enough hardware to make 700+ to the tires... I'd probably go to a smaller blower cam though for driveability.

Boost level will depend on the pulley combination..

 

Might wanna try some lsa heads over the l92's plan on more then 500rwhp with a f1a

 

And it won't make same torque as horsepower. Sounds like your gunna have your hands full.

 

Hell he could leave the blower off all together and make 500rwhp...

 

If that thing only made 500hp with all that done and a F1A kit and it were mine, I'd drive it straight off a cliff

 

500 can be on a stock motor and p-1sc easy. Meth and do not tune for meth.

 

As others have said, you will be struggling to stay as low as 500 with what you have listed.

The FAST will be fine with boost, but certainly not needed. A Stock LS6 intake and TB are more than adequate for your needs. A 102mm TB is totally and utterly pointless and will do more to hurt drivability than anything.

 

You will clear 500 no problem. I made 550 on 8psi stock ls1. That thing should make some serious power, good luck.

 

I went back over your build thread again are you using the 232/240 blower cam?

The 402 did make over 500hp & 500tq on a mustang dyno NA but that was with 11.8 compression, large exhaust system & a larger cam.

I am pretty sure it will make over 500 to the tires but I don't want to focus on making the most power and forget that I just want to enjoy this one.

I plan to run the kit right out the box, so hopefully that provides enough boost.

Whats the difference between lsa heads? Can I swap over my L92 valvetrain?

I see what your saying, a stock type intake would be fine and support power goals. I would have to look for a LS3 intake though since I'm using L92 heads.

 

The above Mustang Chassis dyno graph is from a 2005 CTS-V that we built at the old shop. We started with a new LS2 block, added a 4.0 stroker crank, Diamond pistons and Total Seal rings. Compression ratio is 9.5/1.
We used our 232/240 595/608 on 115. We topped this off with off the shelf AFR 225 heads and a FAST 92 intake. Kooks 1-7/8 headers were used and a ProCharger F-1A.
It made 864 rwhp at just 12.4 psi of boost. Take a look at the torque at just 2000 rpm, this combination is very street friendly. The owner of this V (skydiver on here) took his car to another shops dyno day and it made more power on their dyno. Bob

 

Yes has been in the car 3 years now. Love it.

 

Thanks for that! Between you and josepy you have me sold on that cam for my setup!

Anyone using a polished head unit? I am trying to decide if it's worth the extra cost or not. I don't think it can even be seen from up top can it?

 

Have it! And can't see it! Will my f1-a be polished? Yes! Why? I keep asking myself same question

 

No need for a polished head unit unless it was a corvette. Our headunits mount down low and you can't see them at all.

The forumla for making 700+ is pretty easy anymore on a stock cube motor. Forge the pistons and rods, compression at 10.1-10.5, decent heads, long tubes, D1SC with a 4.00" pulley, Aster's bracket, FMIC and you're looking at north of 700 rear wheel horsepower.

It really is amazing.

 

goal of 500hp/tq?
i laughed so hard at that when i read the build. your kidding right?
