So I was planning to purchase a set of 18" RTS wheels and tires but now considering putting that money (~$3200 max budget) towards piecing together a budget procharger (p1sc) setup instead, as I would love to push ~550-75whp if I can do so reliably. ( that sound too!)

Given my power goals, budget, and stock bottom end I felt the P1 would suffice for now. In the future, I would forge the bottom end and upgrade my trans again...then most likely go ***** to the wall and jump straight to an F1.

However, after researching tons of threads, I have some questions and concerns regarding adding one to my specific setup.

Car: 02 SS A4 (68K miles) - Summer weekend street car only

Current setup: ~430'ish whp
- TSP 228r 112
- GTP white 36#injectors (~41# on LS1)
- 243 heads (light bowl/VJ work, no milling w/ OEM MLS gaskets)
- Fast 102mm Intake with NW 92 TB
- SLP 25% UDP
- Level 4 FTP 4L60E with Yank SS3600


1. Is my current setup FI friendly or would I need to swap heads/springs/intake?

2. Would I easily surpass my hp goal, even on 5-7#'s, and find myself in a position of rolling the dice on my bottom end and trans. If so, I guess it would be better to hold off and build both up before slapping a procharger on?

2. Would my injectors be enough for 550-75whp or will I need to upgrade to 60's period? I know I will need to upgrade to a Racetronix fuel pump w/ hotwire kit?

3. Anyone have any experience with a FLT Lvl 4 4l60e and whether or not it would be able to handle the power? (trans not horsepower rated so just looking for some input based on personal experience)


Complete noob to FI so thanks so much in advance for your input!

What's your compression? The heads and intake will be great, but the cam is not optimal. You will need bigger injectors; 60 lb/hr would be good. Your cam will work though, but just not optimal for a Procharged setup. What's the rest of your fuel system like?

Stick the blower on then fix whatever breaks lol

I'd probably say go with the D1SC too, it will take you further and may even be enough for future goals and means just a single purchase

D1SC will give you plenty to grow off. Plenty of threads with guys making great numbers with these. I would think 550 will be easy with your setup now adding a D1.

I broke 2 4l60s at 700 ish rwhp so I don't have much faith in them

I have to agree with the other guys on going with the D1SC. That blower is very versatile and you may be surprised how much it can make once you've got a fully built engine.

I went from 389 RWHP to 604 RWHP by adding the DSC1 Pro-charger and a meth system. 2001 Camaro Z28 with a LS 6 and a baby cam.

Go with the D1sc if for nothing else, resale value. People are always looking for D1's, but P1's are tough to even give away.

Basically stock compression (10.5.1) since the heads only had .005 removed during cleaning. Outside of my current injectors and some Holley EFI Hi-Flow fuel rails my fuel system is stock. The cam may not be optimal but if I go this route I will keep it, as I don't want to go tearing into the engine again right now.

So without changing anything on my current set up and adding the following supporting items, how much boost/pulley size should I run to keep it around 550whp... 600 max?? (P1 or D1)

- 60# injectors (selling GTP 36's)
- Racetronix 255lph w/ Hotwire kit
- Ebay CXracing FMIC + Piping
- Proflow Bullet bypass
- Spal fans and mount
- Truck filter/hat
- Boost and Wideband gauge

You'll need the bracket, plus pulleys (crank and headunit)

Brien, do most of the brackets come with the pulleys, or do you buy them separate?

Start with the D1SC and go from there.

The Alchemist

The brackets come with the pulleys for the bracket, but I was talking about the crank pulley as well as the head unit pulley. Might not seem like much, but the 8-rib ATI balancer/pulley is a good $350+ and a head unit pulley is $80, although you should be able to source one used for cheaper.

well you havent had a properly built 4l60.. my rpm level 6 laste at 900whp for months.. anything will break if not built to withold the power

stevieturbo

IMO just buy a complete kit...it'll save a lot of headaches, especially if you arent really familiar with what you're doing.

Trying to piece stuff together can be a nightmare.

Broke 2 input shafts, 2nd one was a billet piece. That thing is tiny compared to the 80 shaft. Had nothing to do with who built them

Here is my complete system that includes the balancer, crank pinning kit, injectors and fuel pump. It has the option for the Aster bracket, which I recommend as you're planning on a larger blower in the future.


If you want to piece it together, take a look at these two links.

I know I will probably catch flack from some but I picked up a P1 head unit freshly rebuild with zero miles for a price I couldn't pass up (under 1k shipped) and would work for my budget and goal.

Few questions before I place an order with Bob and other purchases:

1. What size pulleys (crank/head unit) do I need to make 7-8 psi with my current setup?
2. Will a Racetronix 255 w/ hot wire kit and 60# injectors be fine? (planning on running a Snow Performance Stage 1 kit as well)
3. Big Red or black Proflo bypass valve on FMIC set up? Proflo valve work with truck hat/filter??
4. Has anyone been able to mount a FMIC and keep some of the foam bumper? Leaving some around the intercooler?

Are you going to go six rib or eight rib? Bob

I was planning on just using the 6 rib so I can then use my stock balancer. Do you strongly suggest I switching to the 8rib on my p1?
