This is the best way I can think to explain it to people still hung up on peak numbers. The following dyno graphs are SPEED (MPH) vs TIME (seconds), showing the best two, and worst two spacer runs, and the BEST two stock runs (worst two runs were omitted because they sucked so bad). All of the runs were started at between 34 and 35mph, most within tenths of each other.


First run to 100mph was with a spacer. BOTH of the best stock runs are still slower than even the worst spacer runs! 7.5 seconds from 34-35 to 100mph


First (and BEST) stock run to 100mph @ 7.7 seconds, with the 2nd best still trailing while all of the spacer runs pull ahead by a minimum of .5 mph up to 2.11mph faster than the poor sap without a spacer.

The spacer makes torque, which is what moves the car! Power is derived from torque.

0-120 MPH, given the same mods, the car with the spacer WILL beat you, regardless of having 3-5 HP less than you.

Before anyone says "So if I put a spacer on, will I gain .2 on my 1/4 miles times?"... NO! There are far too many factors that are to be considered at the track vs on a dyno which is CORRECTED for OPTIMAL conditions via STD, or SAE correction. The load on the drivetrain is completely different, then you figure real life weather, track prep, track temp, tires/traction, driver abilities, engine temps, 60ft times, etc etc etc... In a PERFECT world sure you might gain .2, but the sad truth is that this world isn't as "perfect" as corrected dyno numbers.

That said, in my personal opinion, the ONLY think you are loosing at the top end HP is simply a small amount of a number that means absolutely NOTHING as I've just shown.

Here's one more for the road...


I've added the WORST 2 runs after I've added the ported intake. Both of them started off as the slowest speed at the start of the run, one by a full mph... They both overcame the best of the best to finish first with the spacer installed. Note that the best spacer run (purple) and the best stock run (blue) started at nearly identical MPH at the beginning of the run.

I'm not trying to convince you, or anything. Just hoping to educate some people that peak HP isn't all it's cracked up to be. In THIS PARTICULAR case, it sure looks like a BIG GAIN from 0-5000, out weighs a SMALL LOSS from 5000-7000. By the time the competition catches up with that loss, you've already won.

This intake manifold spacer comes included with the G8 oil cap extension so you can keep your engine cover on!

Selling for 125, shipping included. The original price was 200 not including the 9 dollar oil cap extension.
