You must be reffering to a Paxton 585rwhp since it doesn't get much more than 20rwhp over stock and little torque increase until after 3500rpm. A Roe makes MAX torque immediately! Your n/a will make more torque than most Paxtons (except big kits), but it's nowhere near the probable 590rwtq@ 2,000rpm that a Positive Displacment (Roe) supercharger makes.
It also said "at 5# boost". My 10# boost makes about 800rwtq and 720rwhp. My car went 10.5@139mph on stock tires with the Roe. Not saying that you should get a Roe, just don't expect to be able to beat one. My 8.5# Roe with all stock except Cat and back exhaust made 598rwhp and 644rwtq for about $8,000
All engines experience "heat soak". Turn off your engine after driving it, turn the key back on and watch the temp guage go up. If you run nearly anycar 'back to back' you'll notice that they all slow down the more they heat soak. Some more than others. There's ways to minimize or cancel out heat soak. Dry Ice, wait time, fans, Nitrous Oxide works well, water/**** inj., C0 is sometimes used. etc. etc.
You can't put much boost on a car with 10.2 comp, that's one reason for the 5# pulley - don't melt the cast pistons - but once you instal forged 9-1 pistons you can run much more boost without melting the pistons out of the motor.
Roeracing has a Gen3sc system for the SRT10 pick up (see
Roe Racing Performance Parts), but it's intake is on the top. Wanna chop your hood or add a scoop? I con't see why it wouldn't fit as long as you have a hole in your hood. I haven't asked because I have a Gen2. Since it seems that some people have an issue (?) with Sean, you could call Larry Macedo and ask him to build it for you. My engine was done by him and it's reliable.
I bought a front axle big brake kit from Sean last week. It was $1000 cheaper than the other site I priced from on the internet.
I love my Roe so much that I wouldn't even buy a Gen3 if I couldn't put a Roe on it. Besides, I love my Gen 2!
