So, I am just seeing what the interweb has to say about this, but I have a Paxton supercharger I got as part of my engine when I bought it. Unfortunately, when we tore the engine apart (due to low compression in one cylinder) we found out it had a cracked piston. So, we ended up stroking it. Now I have this really cool 408 built by IMM and I'm just curious, could I put the Paxton on it in the future without possibly blowing it up? The Paxton (NOVI 1200SL) has just sitting in my garage for years.
This car is going to be a cruiser/race car. I originally built it for autocross, but I may transition over to road racing a couple times a year. I also do plan on just cruising it every weekend for a minimum of 10 miles, but may want to take it on some road trips.
It has a full 6-point cage, hotchkis suspension, 1.18 TB's, T56 Magnum transmission, and an 8 3/4 built with all Dr Diff parts (3.55's and Eaton True-Trac). So it's built for power. I don't really abuse it (hard launches). My limiting factor is tire as I'm only running a 300 TW 255/40/18. My next step is for a 200 TW 265/35/18, possibly a 275, if I can make it work.
Right now the 408 has the following parts:
Forged pistons
I-beam rods
Forged Scat crank
Engine Quest ported heads
LD4B port matched to the heads
Customer (aggressive) cam
9.6-10:1 compression
It made 523 hp and 522 ft-lbs of torque at the crank. I ran it at Willow Springs and I just want a little more power so I can keep up with the Hellcats.
If I do this, I'm going to install a Fitech on it first. I'm kind of tired of the rough start ups. Once I get that sorted, then I would move to the supercharger, but I won't run more than maybe 4-5 psi of boost as the trans is only rated for 700 ft-lbs of torque. We can only get 91 octane in CA and I'd rather not run water/meth injection, but it's an option. If anything, although it would be busy, I'd add a water-to-air or air-to-air intercooler.
What are your thoughts?
