First Impressions / E-Force on LS2

- You've added 60% or more horsepower to the stock engine
- Headers even if coated are going to add underhood heat
- The 70lb chunk of mostly aluminum that now sits where your intake manifold used to be and the fact that it will eventually work it's way up to about the same temp as the engine block
- The s/c heat exchanger that sits directly in front of the stock radiator.
I don't think it would be any surprise that you'll want better cooling than the marginal when stock OEM radiator....Dewitts
As for the sound...I can't say enough about the "Dual Mode/NPP" factory option....loud when you want it and whisper quiet when you want to be stealthy.

This was a very sad sight to see when I went to lunch back on 20 July!

OOOhhhh, its like I park my vette out away from everyone else and there just so happen to be a run away car in the parking lot and it just so happens to hit yours! Sorry bud but at least its an easy looking fix.

This is what I am having trouble with, if you look at your setup, minus the eforce, you should be around 475 + rwhp N/A. Going by the rule of thumb of 20 hp per pound of boost the eforce should add about 160 hp. I don't understand why you are not in the low 600 range? I was on the camaro forum this morning and a stock LS3 camaro was making the same numbers as your moded ls2. Do you think they tuned it very conservative?
Once you add the cam and eforce any exhaust is going to get really loud, you may try the magnaflow again, you maybe surprised!

RE: Coolant temps, What were you seeing before? Without a custom OS the fan tables only go as low as 192 degrees and you can't command anything in that cell unless you want the fans to be on all the time. So you can only command more fan from 196 and up. I recommend 90% from 199 on up but you will have to watch out for cooking the wiring harness behind the raridator fan. So you can see that even with a 160 t-stat it's going to be near impossible for you to stay under 200.
I had a Go Home Loud exhaust on my VW GTI and couldn't stand it longer than a week. It was obnoxiously loud. I wound up buying a muffler from Cherry Bomb and having it welded in. Things are much more civilized now. (note, the quality of the GHL was excellent, it was just way, way too loud)

Motorhead47, don't worry about hijacking my thread. Your posts have been a big help to me in deciding which system I went with. I feel for you. I almost got nailed this morning after having the CEL corrected. They forgot to turn off the rear O2 sensors, but all is well now. As for the cooling concerns, I'm already in the process of addressing that. I got a price on a Dewitts and a BeCool radiator. Surprisingly they were in the same price range so I'm open to suggestions on that. I've considered draining some of the coolant and replacing it with Water Wetter. I've done that on my street rod and it made an appreciable difference - especially when sitting in traffic (cruises). I know I live in Michigan, but we've had more 90+ degree days here this Summer than we've had in the past 15 years put together. Maybe I should have been listening to Al Gore on those "ozone action days" instead of filling my tank. As for the exhaust, I'd say the jury is still out. The car sounds great on the outside and in drive by's, but it sure reminds me of my age when I'm accelerating through the gears in traffic. Oh well, at the rate I'm going I'll be able to say I've tried most of the major brands of aftermarket exhaust systems by the time I'm done.
vertC6, I would think the tune leans in the conserative direction. I haven't specifically addressed this with them, but I honestly don't think they would start with an over the top tune unless they knew that was what I wanted. I didn't have any preconceived horsepower expectations, but the results were very close to what Livernois had predicted. My guess is there's still more power available, but I'm sure it would come with a trade off in terms of long-term dependability and increased parts failure. Right now, the results are far more than I expected and enough to keep me happy - at least, for a little while.

I was going to make a post, but didn't realize you already did.
I based my HP "guess" off similar Camaro's we've done with a Magnacharger and similar parts and your car made slightly more than they do.
A Camaro that makes 550 RWHP and weighs 4000 lbs. will run 10.90/11.0 at this power level, so you definitely have a 10-second car if it hooked.
Here is a video I got of it on the dyno

Have fun and be safe

It was definitely much quieter with the Magnaflow system, but for some reason still freaked out the microphone in the camera. It sounds funny in the video, but didn't sound that way in person.
We should have video taped the "drive by"!

Talk to you soon,
Rick




















I'm very interested in this as I am contemplating going the E-Force route with my 07.
