Got the call from Jaime at StreetSideAuto<\/a> that my Spectre Performance custom STS-V intake is on the way here; it appears to be set for arrival Mon\/Tue.\u00a0 I called and set my dyno day with Tim at True Street Motorsports<\/a> in McKinney for Friday, August 5 beginning at 9:30 am.<\/p>\n

\"\"<\/a><\/p>\n

The plan will be to dyno my 2008 Cadillac STS-V in stock configuration, swap on the Spectre Performance custom intake, get the STS-V back to the same conditions as start, then re-dyno with the intake.\u00a0 We’ll be monitoring IAT, IAT2, and fuel richness among other things.<\/p>\n

Dyno runs are normally done in the gear closest to 1:1 which in the STS-V is 4th gear.\u00a0 In sport mode the STS-V can manually shift and hold gears, which is dyno friendly.<\/p>\n

It is very hot in Texas this summer, and likely will be 103F still on Aug 3.\u00a0 Stock 469 hp STS-V’s tend to dyno at 360-370 wheel hp, for a ~23-21% transmission & rolling loss.\u00a0 So that’s what we might expect for the baseline.\u00a0 Other users have reported as high as +40 whp, up to 410 whp, but there are very few controls on internet reports as to whose car is truly, strictly stock and not.\u00a0 Judging by ‘normal’ automatic vehicles 20% transmission & rolling loss, that would put the V at 410\/0.8 = 512 hp equivalent.<\/p>\n

I am hoping to get to 400 whp, but the whole day is an adventure, so we’ll see.<\/p>\n

As you can see from this view of the ‘back’ of the LC3 in the STS-V, the intake tubes run all the way around to the back of the engine.\u00a0 That large box along the way is a silencer to remove or mute the sound of the supercharger.\u00a0 The new intake is just straight flow, so the V will pickup a pronounced supercharger whine.<\/p>\n

Then I’ll enjoy the car for a couple of weeks, and return to the dyno for a “2 week laters” test to see if the improvement is sustained.<\/p>\n

What do you think?\u00a0 Any advice?\u00a0 Please add a comment!<\/h2>\n
