[QUOTE=reasonable suspicion;1589340389]Jason,
what is the exhaust setup on this car?
LG 1/7/8 longtube headers, factory NPP exhaust with dual QTEC 3" electronic cutouts.
Cutouts made no difference on the dyno...
Before the car went to Katech, the only mods were headers and cutouts. The sound truly had to be heard to be believed! Can only imagine what it sounds like now. https://www.corvetteforum.com/forums...ilies/rock.gif
I am the owner but I have not yet seen the car since it was completed. My employer has very strict rules about time off.

haha, I saw your car Thursday....sitting in the corner with plastic over it.
Stock headers? I ask because the torque is low and thought it may be due to stock exhaust. Unless the cam is really mild or there is not much compression

doesnt look like he milled the heads. He has lg headers

Heads are factory 11:1 compression. I move around the country frequently, and wanted to be able to run 91 octane if needed.
The baseline was with LG headers only and exhaust cutouts only.
Although the dyno shows a loss of low end torque, the K501 actually makes about 440 ft/lbs at 3500RPM. They just couldn't get an accurate reading on my car at low RPM when it was dyno'd. There are plenty of other dyno charts on the forum and the Katech Facebook page showing this.
sure did....he was just puulling your car out for the dyno when I was leaving. beautiful car, love the yellow!
They have a full shop, maybe 12 cars in line
what are you having done?
Cool! thanks for the update.
My build will be similar to SN#76, except I'm adding GM high speed lifters; Dewitts radiator; ATI dampner; Ti/Mo intake/Exhaust valves;Katech billet belt tensioner;Katech billet fuel rails, Katch valve covers powder coated VY; coil relocation kit.

Nuclear, I'd be happy to deliver your car. No charge. No problem with my employer, as I have none. Would be very careful not to rev. it above seven grand and nothing above 175 mph.
