Katech Preliminary LT1 engine dyno Results
The dyno below adds the results of swapping out the Halltech alpha prototype, with our beta prototype. The beta model improves velocity, and fills in the torque and horsepower drop offs. +2 to 11lb-ft throughout the curve, and +2lb-ft peak torque to 510 HP/ 505lb-ft torque. The A-B swap was off course done with the Katech dyno headers onboard, but one could expect this bump in torque/hp when comparing the Beta PT to stock. That would be +13/10 over stock (STP) and +12/9 (SAE).
Key: red line:Halltech beta prototype, Katech dyno headers.
black:Halltech alpha prototype, Katech dyno headers.
green: Halltech alpha prototype, stock headers
blue: 100% stock LT1
The B-prototype goes to beta model in 10 days or less. Once we get the working model, it will be tested (not on the dyno since those numbers are firm), and we'll have our C7 and Katech's C7 running the intake dynamically, logging everything.
Yesterday we ran several 1/4 mile sprints with our B prototype, and no heat shield. We had zero knock retard, even though the IATs were +30 to +50 degrees over ambient. (The heat shield will bring IATs down to +5 ambient. Lots of testing going on.
Production versions may be ready by November 10th.
This dyno was done with the dyno headers still in place, so the numbers don't look like much, and the peak numbers remain 13 HP/ 10lb-ft gain for the intake, 10/17 for the headers. But look at the under the curve torque. They curve is straighter with from +2 to +11 lb-ft more than the alpha prototype. +2 lb-ft peak gain to 505 lb-ft.
These are the numbers so far:
C2-10133 Stock intake
SAE 464/457
STP 487/478
C2-10138 Halltech Intake A Prototype, stock headers
SAE 476/464 +12/7
STP 500/486 +13/8
Dyno headers and A Prototype:
510/503 STP
With headers and B Prototype:
487/482 SAE +23HP/25 lb-ft over stock
510/505 STP +23/27lb-ft over stock
The new beta Prototype will be a bolt on carbon fiber unit requiring no MAF re-calibration at all. All the above dynos, including the Halltech pulls were done with the same air fuel ratios as stock, timing, etc. No tuning changes have been made to any of the pulls.
