Thats one thing I dont like about NA.
My old, old "cheaper" H/C setup made 430/400
LS6 intake & ported TB
stage 2 ported 5.3 heads
pacesetter Lts
Comp 230/230 cam
UD pulley & lid
Magnaflow catback

Then I decided I wanted more. I see all these guys making 470-485rwhp with a H/C setup. So I bought a complete motor off of a member from this site.
here was the specs on it:
FAST 90/90
85mm MAF
AFR 205 heads
G5X4 cam
Kooks LTs
Lid & UD pulley
3"duals


Dynojet#1 It made 455rwhp (tuned for 75mm MAF)
Dynojet#2 It made 457rwhp (tuned for 75mm MAF
Then on a Mustang dyno It made 464rwhp (tune corrected for 85mm MAF)

My point is the second motor had the best of the best ($$$) and a much bigger cam and only made 34rwhp & 14rwtq more than the "budget" H/C setup

Also, Just because you make a certain number on a mustang dyno, dont assume your going to make more on a Dynojet. I proved that.
The most over used line on this site - "I made 450 on a stang dyno that means im making 500 on a dynojet"

 

Ya I hear you, I dunno its hard to make up my mind. FI is sweet but with that Id need a new clutch and rear so its quickly well over $10,000

 

Head cam + FI or just FI. If I had to do it all over again I would have never done head / cam / headers / intake etc etc. Straight to turbo or procharger.

 

100% agree....
H/C + FI on a stock bottom end = big power
or
Forged shortblock and boost the hell out of it = big power

Im installing stock LS6 heads & LS6 cam & LTs now for a mild yet fun 390rwhp and then planning on a P1 or D1 and 7psi for a nice 550+.

 

Bringing this back up. Hows the torque down low with a P1 or D1? Since the car is strictly a street car, Im wondering how the power is down low without having to rev the **** out of it to see boost compared to a H/C setup with power always there..

 

A stock cam with a blower will still like rpm. I drove a friends car with headers and a p1sc and it was sweet. Pulled very hard yet drove like stock. I just love a cam sound and instant Tq.

 

So your saying the torque on it wasnt instant? Revving up high is pointless for me on the street.

 

Its not instant like a twin screw or roots style supercharger.
I would say a P1 or D1SC with 7-8psi would feel like a strong H/C car. Without the lope.

I will also say with just normal driving, out of boost, My 2001 P1SC car felt more powerful than a stock WS6. I was suprised by that because I thought since your out of boost, the engine has to use power to spin the supercharger....but then again even when your out of boost, that P1SC is still pushing alot more air into the engine vs a stock LS1.

 

Oh how I wish Whipple would produce an LS1 kit without extensive modification to the cowl..
This basically answered my questions in one post. A P1 or D1 would be what I would run at that psi. Guess H/C/I is the cheaper route and the route that would be suit what Im looking for. Thankyou sir.

 

You might wanna research that statement a little more

 

The cost factor?

 

Don't forget about suspension, its all for nothing if you cant hook.

 

yep yep

 

We'll I dont have much for suspension and I can tell you 600/600 out of my old twin turbo setup was still fun on the street. I know suspension would help alot if you are after ET and go to the track alot but I wouldnt call it a necessity for fun on the street.

 

I priced out the heads/cam/ported intake/lid/TB and everything needed for the install just under $5,000. A procharger would be $6,000+ no?

 

not from a stop.

 

Heads/ cam/ intake isn't cheap either... Price it out before you decide. Don't forget to include the price of gaskets, bolts, the value of your labour, and any other misc parts. For example I paid 450 for the intake, 500 for the heads, and about 300 on cam, push rods, and shipping.. But I also spent 150 on springs, 180 on head bolts, 150 on head gaskets, 140 on a set of used headers, 50 on a used lid 1300 on header install and tune and I also lost a whole week of my time. Oh and at least 500 on needed tools. That's nearly 4000 bucks...

 

We'll Ive always tried to buy quality used parts from this site and that has worked well for me. A 450rwhp H/C setup price list looked like this for me.
(I used stock injectors & fuel pump and made 455/413.

TFS or AFR heads used 1500
Cam (new) 400
used FAST 90mm 600
90mm TB (new) 375
LT headers (used) 350
Y pipe & catback 600
U/D pulley (new) 200
gaskets & bolts 135
Lid 100
Pushrods 120
4380 total

P1SC kits goes for $2800-3300 on this site. I just bought a P1SC kit that was 90% complete for ALOT less than that.

This is just a comparison for H/C vs a P1SC kit looking to make 450-460rwhp.
Eventually, either way you go, your going to need a aftermarket clutch or built trans if your a A4.

And if you go with a large cam, ya better add a set of gears to that list. A big cam is going to be "begging" for a set of gears more than a FI car running a stock cam.

Hey - Both setups are very fun, close in price but the potential for making alot more power down the road, FI wins. Since Ive had both, Im just giving you my experience on this subject.

 

^I appreciate your imput. I have the exhaust all squared away with whatever way I go. I also would need a new clutch with whatever route I went. I never really looked for Prochargers on here used, I didnt realize they go for that cheap. If I go FI I wouldnt want a big cam, just something that compliments the SC and gives a little lope.

 

You're doing something wrong dude.....
