Default LG Super Pro Dyno #'s

I had 1 3/4" LG Super Pro Headers (no cats) installed and dyno tuned at Horsepower Sales yesterday. The car is a 2008 M6 with NPP. It had a Callaway Honker and a 160 stat installed prior to the baseline pull. Also installed MSD plug wires, NGK TR55 plugs, and a Royal Purple oil change at the same time as the header install and tune.
I gained 42 rwhp and 38 rwtq.
It runs great and sounds like a beast!
Thanks to Jeremy, Roger, and the crew at Horsepower Sales!

Um...am I reading it right that it says you made 461/464 with intake/exhaust/tune? I think we've just found one of the most generous dynos in the country

Good gains from before/after though.

Great gains before and after.

Mustang dyno, it looks like? Doesn't list the correction factor so the numbers look a bit high to me as well.

The difference gain on the car and same dyno look very good! Congrats!

Hey Gary,

Thanks again for the business. The LG's made that thing sound killer

We have asked Mustang dyno a few times last year about the setup specs they put in when they first set it all up last year. They swear its fine so we just let it roll.

This is also why we always do the before and after pulls to see the real gains and then take her to the track

Thanks everyone,

Jeremy

I think those are normal gains. Enjoy

Awsome numbers, you have a beast! I will be on their dyno next Thursday to test my new Heads and cam. Hoping for 460-470 in my LS2.

Can you PM me the cost of this set up. I have been on the fence for some time now.

Does it matter that the graph says engine hp and engine tqe? Makes me think that its giving the gains as flywheel hp and not rwhp. Don't know if dynos even have the ability to convert the rwhp to engine power (through some conversion, not measuring directly?) If that is flywheel HP the car is right where I would expect it to be. Whatever it is the gains are as to be expected for that setup.

I never saw those kind of gains across the boards with the mods that were done either. Something seems fishy.

I gained 47 rwhp and 41 rwtq with AR 1 3/4 catted, tune, plugs and 160 degree stat. and vararam.

On Dynojet SAE best was 422 both hp/tq.

Gains seem about right, although your total is reading like a medium cam was added too.

So the gains is the important thing but I would question your overall numbers.

Hmm, 40 HP increase doesn't seem that unreasonable with those mods (depends how "tight" your bottom-end is). And, the VaraRam doesn't even enter the equation until your velocity reaches about 50-60 MPH, then you should see another 25+ HP on top of that!

Those numbers seem really high.

I have a 2006 coupe w/LS2, 6speed manual.

Here are my horsepower mods:
LG SuperPro 1 7/8 Longtube Headers
SLP Blackwing Intake
MSG ignition wires
Tuned on dyno at Rocky Mountain Competetive Research in Colorado Springs, CO.

Dyno'd at 380rwhp and 375rwtrq. This is with the correction factor as we are at a 6,000 foot altitude above sea level.

That is, without a doubt the most 'optimistic' prediction or proven hp gains with any intake I've seen.

The LS3 intake is just fine unless your tracking and want the lower intake temps.

No way those number are right. That's closer to what I'd expect for a Z06.

I agree with the above. I was reading this thread yesterday and I was blown away, thinking my car was a POS. I just had mine dyno tuned:

08 M6
ARH 1 7/8"
Halltech killer bee intake
Borla Stingers

427 RWHP
434 RWTQ

So, yeah, I think those numbers are grossly inflated.
