SPEED INC. FAST LSX-R - NW 102mm TB dyno test I finally had some time today to do some testing with the new Fast LSX-R intake manifold and Nick Williams 102mm throttle body.
Vehicle specifications-
2008 Z06, 5k miles. Speed Inc./Comp 228/242 117 cam, ported LS7 intake manifold, stock throttle body, Vara-ram induction, Kooks headers and X-pipe. No cats. Stock mufflers.
Test specifications-
All dyno runs were made with water temp at 200deg and oil temp between 190-200deg. No cool-down runs were made, I wanted absolute consistency. I made three baseline pulls and three pulls with the FAST intake/NW TB. The car was not shut off between runs but was allowed to idle and cool back down to 200deg temps before the next run was made. Anyone interested is welcome to the HPT logs.
The tune remained the same between both intakes with the exception of some etc scaler and idle airflow adjustments for the 102mm throttle body. Air fuel ratio is 12.85.
Stock LS7 injectors were used for both tests and they were reaching 89% duty cycle.
Conditions remained very consistent throughout the day. Baseline was between 85.13deg to 85.71deg, 26-27% humidity 1.02 correction SAE.
FAST runs were between 82.29 to 82.84deg, 27-28% humidity 1.02 correction SAE.
Test results-
Baseline runs with ported LS7 intake and stock throttle body-
Dynorun 54. 513.85rwhp 458.71rwtq
Dynorun 55. 512.10rwhp 457.69rwtq
Dynorun 56. 512.29rwhp 456.61rwtq
Test runs with out of the box (untouched) LSX-R intake and NW 102tb
Dynorun 57. 526.09rwhp 481.39rwtq
Dynorun 58. 528.84rwhp 479.98rwtq
Dynorun 59. 528.49rwhp 479.35rwtq
I was rather impressed with the results. Comparing the best ported LS7 run to the best FAST LSX-R run, gains were 14.99rwhp and 21.27rwtq at peak.
In other parts of the curve gains were up as much as 23rwhp and 23rwtq.
