I am posting this here since it is about the tech/install of the two.

So far I am leaning toward the paxton for the following reasons:

1: ECS is a great company and Doug and Chris developed the now stolen design of the ATI. I didnt like the shady move Procharger did in making entire kits forced upon the tuners that support this forum.

2: The paxton according to Doug doesnt require the cutting and relocating of the lower radiator mount.

3: The NOVI 2000 is bigger and provides more boost with greater efficiency than the P1 and D1. It is between the D1 and F1 s/c's.

My issues are:

1: The ATI has a self contained oiling system that is isolated from the motor. In choosing a FI path rather than an expensive stroker/head combo, in the event of a motor failure, it will destroy the stock motor and cheap heads rather than a set of ETP's or whatever....BUT...If the s/c goes it wont share bad oil and the same goes for a failed motor not sending bad contaminated oil into the blower. Something gets saved.

2: Slightly lower price.

I would like any reasonable recommendations, concerns, comments, views, advice, for this car that will not see the track in the forseeable future and while my plans arent to upgrade past the 550-600rwhp range but you never know.

Please dont bother with any turbo, mag, or NOS (which I already have) recommendations. I dont want to go over the 6500 budget by even one dollar. I am not getting the high rise hood either. It is butt. Lets keep the thread on the two choices outlined...thanks

 

Almost forgot....the mods already on the car:

224/230 XER cam 114+2
UD pulley
Kooks headers
RAM clutch/aluminum flywheel
Ported FAST intake: Doug...do I need the trailblaizer TB?
ported TB

Stage 2 heads-not milled but I will replace the existing .040 cometics with stock thickness gaskets.

100 shot: to be reduced just to have a cold intake air charge

 

I truly have no experience, I only have 1k on my Procharger. I love it so far, have nothing to compare it to but my stock motor. Will take it to the track soon to compare to stock numbers, live on the West Coast so went to A&A for the install. So far no problems and since it only seems to kick in when I punch it, this car is truly a daily driver thus far and I am happy with ATI. good luck, PM me for specifics....

 

SpinMonster I believe the ECS Kit uses the NOVI 1200. They claim its good to 700 rwhp.
My understanding is there are some clearance issues with using the NOVI 2000.

PS Dont install thicker Gaskets (CRS Disease cant remember stock thickness).
The reduced Quench will only increase the chances of detonation.

 

Thanks. I am not familiar with the paxton model numbers so I will take note. I mention getting thicker gaskets since I am running .040's which is at 11.5:1 with my stock unmilled heads. I am installing the thicker (stock thickness gaskets) to get back to the stock 10.9:1 static CR. My bigger cam will help there too with dynamic.

 

Yes, they are using the Novi 1200 vs. the Novi 2000. Here is a thread that talks about the ECS offering.

It does require relocating the radiator...but they provide a very nice prefabricated bracket as opposed to ATI where you have to weld and "wing it"

 

Another thing to note is that based on my reading here, the Novi 1200 is one of the quietest centrifugals out there. If you want more noise under the hood, the ATI is the better choice. If you more of a sleeper, the Novi is the closest you are going to get. (or so they say on these forums)

 

I can't believe you're going FI.
Is this a street or track car?

 

 

Anyone have any belt issues....be honest....

 

http://www.eastcoastsupercharging.com/kit_novi2000.htm

their site says its always a Novi 2000

 

Here are a few belt issues, you might want to go over to the C5 section, more of thse guys have SC's. Obviously, there are just as many good stories as bad ones, I'm only showing the bad.

On the P1SC...No! On the D1SC using a 6 rib without the restrictor plate in tact, yes, first run pulled a 664rwhp @ 8+psi and the belt flew off on the dyno...called it a night after that. 8 rib kit would be a smart investment for anyone intending to push the D1SC to radical heights.

Since we're on the subject of ProCharger; my brand new P1SC head unit had bad seals that cause oil seepage to be a concern, ATI quoted $350 for the fix and 7-10 biz day turn around time. I put 1200 miles on the D1SC thus far, and no issues...I regularly check for it.

Last dreaded issue was at WOT, the car would on some occasions go into "reduce engine power" mode, sometimes when I got north of 4K rpms or other times at redline. A&A replaced the PCM with a fresh one and only happened once...contacted Chris at HP Tuners (great customer support!); had Charlie - Under Engine Diagnostics, disable the P0068 test by changing the enable RPM. And also disable the other P0121 etc. codes as well. In the DTC list also disable the P0108 DTC by setting it to "3 - No Error Reported" ...Reduce engine power problem solved!


Good Luck with your choice Guy.

 

Brabus2,

Was the ProCharger problem not covered under ATI warranty?

 

I mentioned this to the tech and he said they would look into it if it's covered by warranty, I stated the unit is only a few months old!!! Needless the say, It would require them to have the unit for 7-10 biz days and I had made up my mind for an upgrade to the D1SC since Andy had one available.

He has one more D1SC head unit in stock, he did say yesterday that he wants to sell it as a kit...but, if your ready for an upgrade, give him a call.

 

Guy....Have you looked into Andy's Vortech kit? The T-Trim should suit your power goal needs. He's got a C6 on the rack right now with an S Trim and some improvements have been made since the last job...I was looking over the install with the tech yesterday.

Cheers,
Richard

 

Maybe they have figured out how to fit the 2000. I know when they the dyno numbers were shown for the new C6 Kit they claimed it was the 1200 because it was easier to fit. Even the 1200 uses a restrictor so they can turn it faster for better midrange without overboosting it on top. I would think the issue would be worse with the 2000.

I am going to wait till winter before any more mods. My tuner told me it'll cost about $1300 for ATI upgrade Pi to D1 and yes it takes roughly 7 days to turn around. I'm sure Andy couldn't sell it for anything close to that, I think new D1 head unit is $2600, and I'll need every dollar I can squeeze this winter. Thanks.

 

Look at the link I provided at the top of this thread. It is Doug from ECS announcing the kit for the C6. In that thread, he said they went with the 1200 for the C6 instead of the 2000 for the C5 because of clearance issues. Maybe something has changed there but I am willing to bet that the website just wasn't updated for the change in unit for the C6.

Quote from ECS: "The kit is very close to our C5 kit, except we are using a Novi1200 head unit and we sunk the air filter down below the radiator shroud since the hood clearance is much lower on the C6. The noise level of the Paxton head unit is very low and can barely be heard from inside the car."
