Default Got It and Love It!

Got my intake manifold and throttle body installed this past Wednesday at Graham Rahal’s GRP Shopnin Brownsburg, IN and only have had the initial test drive when I picked it up and the drive home and I love it! Takes an adjustment for sure to get use to. What it took to get the car to do certain things now takes less effort. Response is much better and did a launch and it’s there. You can also hear it pulling or sucking air in. I’m real happy with it and because we had bad weather move in I e been parked but the engine bay looks sexy as hell!

That looks amazing! Where did you get the CF engine bay cover from (not the engine appearance package)? I also like the info plaque at the bottom, where was that from? I have a Black on Black 2020 built in March (VIN 2352) with very similar specs. I have the manifold on back order (end of April) and already installed the Halltech Hornet last week. Trying to find the best headers to install now and if to do a ceramic thermal coating for the extra heat from removing the exhaust manifold heat shields.

Mine just arrived yesterday! Hoping to have it on in the next week or so but of course i'm now into a Garage Reno (when is anything easy?!) so might have to push it off a bit. This thing looks amazing; thanks Harding Performance!

Do you have the ability to do a before and after dyno to verify horsepower numbers? Haven't seen a single dyno yet show their claims of 25rwhp with the intake alone by itself.

Probably because that's not what they're claiming. They're claiming +25 Hp WITH the 95mm TB. I haven't seen any claims on just the plenum.

I swear I thought I saw the claim was with the intake only, but either way, I still haven't seen consistent proof of 25rwhp even with the TB outside of the dyno from the manufacturer/OP. It sure does look nice though.

I'd really be interested to see some dyno sheets of cars in the wild backing this up. Look forward to seeing that.
