Pulling carbon traps

[LavaRed50]

18 is greater than 14. Looks like may need to update the 5.0 badge and add an extra zero?

Glad to see someone came across my short video. I actually posted a longer in-depth video this morning. For those wondering without watching, the car was heat soaked then 2 pulls were made 100% unmodified, then 2 pulls made after removing carbon filters. The car was started and ran through the gears for a minute or two on the dyno to ensure the same amount of heat was in the engine. The pulls with and without filters were 15min apart from each other. 16whp 17wtq throughout most of the rpm band. Pulls were made in 5th gear to reach 7,400-7,500rpm. I've also verified the car runs a lot better against friends cars than it did prior, but I won't post those videos. There will always be skeptics, which there is nothing wrong with!

Was it not 413 to 431?

The Dyno before that showed 421rwhp

421 was a 6th gear pull we did when we first picked the car up, but the car hit a top speed limiter and rpm stopped at 6,800. I wanted a comparison all the way to the 7,500rpm limiter, so I did this comparison with all 5th gear pulls all on the same day. Once the cars are able to have speed limiters removed and people do 7th gear pulls to 7,500-8,000, these cars are going to put down some solid numbers.

This I think is the important part of the equation! Running it in the 1-1 gear all the way to redline which cannot happen until the speed limiter is removed.

Middleton Motorsports did a before and after back to back dyno with the carbon filters in and then pulled. The difference was negligible; 1 hp gained at peak and 4-5 hp in the midrange.

The DH has the traps as well, so pulling them could net a gain there, the DH is still going to make more power.

I wouldn't expect as large of a gain pulling the carbon traps on a dual intake as say the 22-23 Mach 1s, as having 2 vs 1 was already less restrictive. I saw someone do a before and after dyno on a 24 GT pulling them and showed no noticeable improvement, hopefully we see more comparisons coming up.

The Mach 1s showed a little bit of a range of gains, probably averaging out around 8-10HP immediately after removal. Didn't need drive time or anything for recal.
