GS Motorsports phenolic spacer results

Hi Everyone,

we want to get this testing done on the Phenolic spacers

These spacers are a super high heat (700 degree) thermal spacer that installs between the manifold and the cylinder head to keep the intake manifold from absorbing the heat, thus heating the intake charge and losing power.


Here is the testing in order.

#1 Warm car to operating temp hood open measure intake manifold surface temp with infared heat gun, also we added tempature sensing stickers to confirm high readings

#2 Dyno car, we had previously based line this car and today dyno was with in 2% of dynos done before so we had a good baseline

#3 Install Phenolic spacers took about 1/2 an hour and brought car back to operating temp

#4 Dyno Car with the new spacers, the hp and tq number showed an impressive gain, so we dyno's 3 times back to back to back to get the car really Hot. The results showed almost no loss of torque and horsepower.

#5 now with the dyno testing done we measured the intake temps again with the car hotter than normal operating temp because of the 3 back to back dynos

#6 Results are a substantial drop in manifold temps .

#7 impressive gains in the low and mid range hp and tq and no virtually no loss on back to back to back dyno runs which before would yeild much lower numbers on the dyno.


All the testing was done on a customers vehicle(Charger SRT-8) with the customer present,

Re: GS Motorsports phenolic spacer results

How thick is the spacer? Anything need to be modified? I know that when I put a spacer on my Mustang, the metal tube running between the EGR and passenger side header had to be lengthened.

Re: GS Motorsports phenolic spacer results

Those gains, if real, look pretty impressive

Re: GS Motorsports phenolic spacer results

I was thinking the same thing, crazy # FOR a SPACER. Hope its true if so I am sold.

Also it hard to tell by their wording .... Was the ManaFlo and CAI installed at the same time? Is this were these #'s are from?

Re: GS Motorsports phenolic spacer results

Seems like some of the gain may be lost by higher ambient temperatures once to hood is closed?

I was thinking the same thing - once the hood is closed, the effect may be diminished a bit. I am sure some folks will buy and test the spacer. If the results are real, which I don't doubt since similar spacers have/are being used with other cars, this mod represents one of the best bang for your buck out there besides the fan mod/ 180thermostat
