So what did you do to your SHO today!?

Installed my 73MM Throttle Body from GPE-Gigs Performance - more air - more air....

I've got the same exhaust setup from PPE on mine! LOVE IT!!!

Not trying to be THAT guy, but the 70mm is already bigger than our intake manifold opening. You might be causing a restriction more than you are benefiting.

Time to break out a caliper.

Thanks for pointing that fact out. When I visually compared the two, it is definetely a larger bore, but tbh I would say there is very little meat to shed.

There is an o ring gasket that doesn't allow for much to be removed with porting

Yup the green one - I replaced mine during the swap. It is big enough to sit flush with the body and clearly larger than the TB hole. This pic is with the stock TB

I am more so talking about the lip of material on the intake manifold being enough to hold the gasket in place. You can knife edge it, but not really much material to remove.

Here is the response from the vendor and excellent catch - you are correct its not 73MM all the way thru - its at the mouth, then tapers in.

"I`m sorry but there is an error in this listing and I`ll need to correct it. All the TB`s I offer where size is quoted are ported to the specified size at the inlet, in my listings it`s stated that they are ported in a venturi style which is a taper so the bore wouldn`t be 73mm all the way through. After receiving your inquiry I checked and noticed that for some reason that`s not stated in this listing, it just says "ported to 73mm". The listing was created 2-3 years ago and this has never come up so I haven`t noticed it`s not worded correctly and any feedback I`ve gotten on this part over the years (and I`ve sold many of them) has been positive.

Part of the reason my TB`s work as stated is due to the 4mm front shaft removal which causes the TB to respond as if it has a 4mm larger throttle blade due to the increase in cross section and less turbulent air flow across the front of the throttle blade as it opens.

There are some porters on the market that will add the ported dimension to the shaft removal if they do it and rate the part larger than it actually can be measured, this part for example could be rated as 77mm:

73mm inlet, plus 4mm shaft removal, equals 77mm

I`m asked from time to time why I don`t spec my TB`s that way and it`s because I`d like a buyer to be able to quantify my specification by measuring the TB at the inlet to come up with the spec I quoted. I don`t have a pic of measuring the inlet of the SHO TB but a couple of pics are attached of an 86mm and a 77mm TB so you can see how my measurement is taken and check to see that the TB I sent you is actually 73mm at the inlet as I quoted in the listing.

I believe this may be a much longer reply than you expected but I wanted to thorough in my explanation."

He offered a return label and full refund. I will however keep it works fine and I can see a difference in response. I am sending some logs to Brad - he asked to review.

I looked up the throttle body in question. I can see what he is doing and yeah technically there is an increase in area that air can flow through. Kind of wonky to say though that the shaft removal is directly comparable to a diameter increase, but otherwise makes sense. (Cuz area of a circle gets quadratically bigger as more diameter is added) Other than the shaft removal the funnel he created is only going to add air flow to the throttle body plate if there is a restriction in that. Long story boring it'll flow more if there is a restriction, which I don't even think we really have and probably the part throttle performance difference is the fact that at a lower pedal position you are just opening more surface area, which arguably I guess you could change pedal sensitivity to get same effect, but wide open throttle is going to be the same either way. Sorry i get nerdy into the numbers with optimizations. This is a pretty recent topic for me as I was thinking about going back to the OEM throttle body on my single turbo build because I don't think it adds anything and disrupts air flow. Now..... If we were NA then I think this would be hawt and I did the same stuff on my NA Coyote truck.

Good pickup Jordan, look I didn't put much thought into it, a fellow forum member pointed it out and the Maxbore store is now gone. I was gonna take my TB and send it out, but they are no more.

I travel for work and will be out of town from this Sun through next week and will still need to log and get Brad's input, I know he is curious.

Cut the rear springs today for aesthetic levelling purposes. Couldn’t believe how simple it is, two bolts to swing the sway bar and a bolt on each side to drop the lower arm and the spring comes out. Cut off half a coil and it dropped it 7/8 of an inch. Almost level and it will probably settle as I drive.

There is a bit of a new clunk going over low-speed bumps. We made sure everything we touched was tightened back up, the spring and spring seals are in the same orientation as they were originally, and there was no play in the wheels. Did anyone else have these light clunks and do things just need to settle more? Otherwise love the look!

Looks great - I haven't heard anything using the H&R springs. Did you check the rear sway and make sure it's not running on the axle housing? Get under there without a jack on full weight. Also since the trunk is huge, you could step into the trunk and give it a good bounce test with another person listening.

Did my first full fluid service (oil, trans + shutter stop, ptu and rdu with shockproof) drained the intercooler, cleaned the tb and maps, replaced catch can lines that were collapsing, serviced the air filter, and replaced the air freshener. Mint

Did my oil and RDU fluid today as well, I’ve finally completed all major fluid changes over that last 18 months since buying the car.

I've had mine for 9 months, supposedly the dealer did the ptu rdu around 85k but the plug looked like this



Not sure if that's normal for a 30k interval but the fluid looked okay and I was pleasantly surprised to find the rdu exhaust hanger already cut. Either way it's done and now since I over bought all my fluids I can do it again next time much easier.

How many miles on her? She looks ok but what color was the gear oil? Is she a PI? Then they maintained it... Keep an eye on it, more frequent changes maybe as well.

She's at 115k, tried to hold it to the 30k interval it appeared it was regularly receiving according to the records (30k, 60k, 85k plus water pump and chains, sold at 87k). But that was a 1/4" blob of metal shavings on that plug so it worried me a bit.

Gear oil was cleaner than anything I saw on YouTube so that was a plus,

and not a PI she is a non pp SHO which made the day really fun extracting it all from the fill hole on the ptu.

Since I have the extra fluid I'll probably do another fluid change closer to the 20k mark and make it an annual thing.

Ok that's right, well keep the oil clean and watch how much builds up, might be a window for a replacement soon. No whining you are good for now.
