Getting back to the mods scene after 10 years with a 18 SS MT. First on my mods list is a Procharger Stage 2 Tunner kit with all the LT4 Fuel things. Goal is a street toy, some 1/4 passes, 600-650RWHP stock block but down the road Cam, heads, etc.



What are these and what are your recommendations:


1. Upgrade Head Unit, P1X or D1SC?
2. 8 or 10 inch rip belt?
3. ATI balancer?
4. Intercooler, standard or race
5. Bypass valve, Standard, bullet or race?
6. gear set, standard or quiet?


Sorry for so many questions, I am a bit rusty and would like to do it right the first time.



Thanks
Jay

Did you look at the Magnuson 2650 for the LT1?

[jwaked]

Not really will look into it but a friend of mine recommended procharger because of the easy to install and the torque is at higher rpm’s since I have a manual transmission. He has had good experience with procharger

I can answer some of those.

1. If you plan to go with a P1SC I believe for $200 more you can get the much more efficient P1x. I regret I didn't go with that. As far as the D1. That is a pretty good choice if you know you want to go for big power down the road. 800+. It can be pullied so that you can grow into it but if you don't plan on going that big on power the p1x is quite capable!

2. I believe you'll be on an 8 rib belt with either of those choies

3. I don't have any info on the ATI Balancer but wouldn't mind hearing from anyone that does.

4. Stage 2 Intercooler. The Race Intercooler is a bigger core and you cannot run your crash bar with it installed. Im sure it would be fine for track only car though

5. Race Bypass is the way to go.

6. Helical cut gears are better imho for a daily street driven car.

Hope that helps!

Thanks man. Quick question, what is the down side of going with the d1sc ($50 more than p1x) or d1x ($225 more) on a stock motor (for about a year )

Thanks

I can't think of any downsides of going with either one of those to be honest. Unless it turns out the bigger units don't spool up as fast as the smaller ones but don't quote me on that. I know the D1's are very well respected and you have a lot more room to grow into those. if you are considering the D1 definitely research the D1x. Also the resale value would be higher likely if you ever decide to go back to stock.

This is what I read at another forum:


"GETTING THE RIGHT BLOWER...

D-1X
Unless you are making 750+ rwhp, the D1X will have a "soft" midrange.
Most will over look this since they usually have a large stalled 6R80.
And want a blower that can support 1000rwhp

D-1SC
The D1SC will have more "hit", in the curve. And is one brutally awesome "street" blower.
Its the "go-to" blower for guys that love roll racing. Power tops out around 880rwhp.
Its just so dang good at what it does, it will never be replaced.

P-1X
Now, if a person is NEVER going to put rods and pistons in their car.
And will totally be happy at 600,700,800 rwhp then my suggestion is the P-1X.
Its got a killer midrange, killer power through full curve, and can support big HP.
This blower is wicked good, and I am sure guys like

P-1SC-1
For guys on a budget, the P-1SC1 is still a great blower... and dudes have proven with the correct combo it can go 9.4's Though that is the end of the line for that blower though still impressive for a base entry level blow"


Now my thinking is (could be wrong) isn`t better a soffter midrange since is a street driven M6 ? I like the P1X and D1SC but need the car to hook up.



Opinions?

[KingLT1]

Where have you seen a P1sc go 9.4's? On a stock weight vehicle that blower would have IAT's over 180 trying to power a car that fast in the 1/4. Fastest I have seen a P1sc car go is 10.0 @ 138 SBE A8 car and it was on 100% meth injection to keep IAT's around 160 degrees at the end of the pull on a 65 degree day.

P1x would be the absolute minimum size Centri I would run.

That being said Centri's don't "Spool" up, they are RPM based of off engine speed. A larger supercharger will come standard with a larger pulley so it won't spin as hard down low, so it will make less boost on the hit and more boost up top. If you pulley the larger Centri down so it hit's with more boost, then you might end up making more boost then the SBE can handle.

Stock LT1's are good to around 10-11 psi with proper fueling and tuning. Some have been pushed harder. The key is selecting a supercharger that will meet your power goals and still operate in it's efficiency range. A P1sc is starting to get above it's efficiency range above 10 psi and right in the wheel house of a D1 at that boost level. @14-15psi the D1 is reaching it's limits and a D1x or F1a94 should be considered.

So imo if you are planning on staying within the limits of what a SBE LT1 can handle, a P1x or D1sc would be my choice. D1sc if you ever plan on doing rods/pistons and turning it up.

I've been to lots of drag races and I'm on the forum all the time and 9.40s is not something I've seen either, it won't happen with an M6 for sure even with an F1 its tough to do, a few have and they have lots of other mods to get in the low 9s and a few in the 8's with lots of Meth and some using NOS also and all are A8's as King said. Its not easy to get there with any blower. It takes the right combination of a lot of parts and a good day with no breakage. Ha I've had my share and you better upgrade your axles, driveshaft, etc if your going to think about making big power. As King knows breaking shit is just part of the game and I'm on that shit list.

[Charlie540i]

My guess is that the info os from a Mustang Forum as a Coyote would do those numbers.

[KingLT1]

All the P1sc coyotes I have seen run high 9's to low 10's full wait and they are automatic cars

[Chevy1American]

Well I have 2 cars over here 1 is a M6 and belongs to one of my customers and mine is an A8 both run full LT 4 fueling and both run the D1X headunit with helical gears the A8 has the stage II intercooler and Race Valve the M6 has the large race intercooler because that car will be going fully forged over the winter and shooting for bigger numbers. On the street the D1X may be a little softer midrange but its not a bad thing, even on 7PSi you will have the tires struggling to keep up on the street (both cars are on Supercar 3’s) what i can tell you is once you’ve got traction they just keep pulling like a train and are pretty much future proof if you do further mods later on great blower in my opinion for the extra few bucks when ordering a system. Installation is pretty easy for a competent home mechanic and can be done easily at home hardest part i thought was doing the in tank LPFP Hope that helps in your decision making

[jwaked]

very cool info. Thanks everyone. Some things are still a bit fuzzy, like why would anyone buy a P1X if the D1SC is only $50 more, and I doubt is because of the $50. What advantage does the P1X have over the D1SC?

[laynlo15]

If I were you I'd call Procharger to clear up any fuzziness you have. Good luck on your choice.
