Finally made it to the dyno today. The goal was to test a new product on the market called Boostane. Add a bottle to 15 gallons, and it turns 93 octane pump gas into 103 octane. I never put much faith in advertisements... I like to test things for myself. Dynojet dyno was used for testing. Engine is a weber stroker, 109 block, std bore, GN1 heads, 218/212 roller, stock MAF sensor, factory ECM. A/F ratio was around 11.1 for all tests. 93 octane with one can of Boostane, no alky or race gas for these tests.
1st Pull:
Baseline. 20psi boost, 18 degrees timing.
Result: 455HP and 492 TQ with no knock.
2nd Pull:
Added boost. 22psi, 18 degrees timing.
Result: 488HP and 518 TQ with no knock.
3rd Pull:
Added boost. 22.5psi, 18 degrees timing.
Result: 500HP and 525 TQ with no knock.
4th Pull:
Added boost. 23.5psi, 18 degrees timing.
Result: 520HP and 544 TQ with no knock.
5th Pull:
Added timing. 23.5psi, 20 degress timing.
Result: 542HP and 566 TQ with no knock.
6th Pull:
Added boost and timing. 24psi, 21.2 degrees timing.
Result: 549HP and 570 TQ with no knock.
By this time the RJC boost controller was tightened all the way in, so to increase boost further I tried shortening the wastegate rod, which caused the boost to spike to about 27 psi. Started seeing knock so we decided to end the testing. And that last pull was a bit of diminishing returns anyways, so that also gave me the signal to stop the testing.
I'm quite happy with the results. 90+ HP gain and 78 lb/ft Torque increase! In third gear it's just ridiculous. 2nd gear is spin city.
