My best so far is 24mpg hiway, but I'm sure I could get better if I tried. lol On my trip home from Detroit last June, I made 660 miles in 10 hours (yes, I was really pushing), I averaged 22mpg, and that includes going through all the toll roads and construction in Chicago and stopping for gas twice.

I also recommend buying HP Tuners and either going to the Precision Motorsports school or getting their learn at home kit. Tuning is fun and can easily be learned by enthusiasts.

I've never had Mike work on my car, but I've talked to him in person and he really knows his stuff.

KPC 67,

James Hatfield at HorsePower Solutions in Edmonton is a name I have heard a few times up here in Alberta.

Matt,

That is one fine Dyno sheet. Am changing my LS2 for an LS7, and would be elated to achieve the same results. Can you tell us what ALL you have done to your motor? And what gears are you running?

Thanks,
Billy Bob

Sure Billy,

It is really just the 430 LS7 that LME from Houston offers. LS7 block and heads (heads have mild exhaust work). Eagle crank with forged pistons, 11.5 to 1 compression. The intake manifold and throttle body were ported and I chose the Katech Torquer cam for the LS7. It is a wet sump motor with a 24 tooth crank and the harness is from Speartech set up with electronic throttle body and cruise control.

I chose the torquer cam because the car is 98% street driven and I wanted more torque (as you can see it worked). The final detail is the PowrMax 100mm MAF sensor that actually added almost 15 rwhp after changing it from the old Corvette 85mm MAF.

The tranny is a reworked T56 from a camaro that can handle 800ft/lbs and the rearend is a Ford 9 inch with 3:70 gears.

Lastly the exhaust is 1 7/8 primary longtubes from Lemons built specifically for the DSE subframe, and the go into 3 inch exhaust with x pipe and Magnaflow mufflers.

All of these parts work well together and the car has tons of power throughout the rpm range, but none of it matters without a good tune and once again, Ed from VA Speed really sorted it out for me!

Hope this helps,

Matt

Davenport in Calgary should be able to help you out - they seem to have one of the best handles on LS engines that I know of in "the neighborhood". Good luck

Matt,

As they say "It's all in the details" and looks like your engine has all the good stuff to make that incredible torque curve. I'll be starting with a crate LS7, and have most of what you have, but your CR, head and intake work, and I suppose the 3 extra cubes, really took it over the top. I can only hope to get close to your specs with the right cam and extras. Talking strategy with Mike Norris tommorow. We'll see what he can pull out of his hat.

I asked about your final ratio as I've been driving my 69 LS2/T56 with 4:10s and although 5th and 6th are ok, 1st gear is absolutely worthless. Been thinking lower gears, but don't know which numbers to choose.
