Haters crazy
Grinded my stocker, no CEL. Just make sure you following the TB reset procedure, and not unplug any nessessary hoses along the way, you wont have any CEL issues! Check out my thread on the TB grind and CEL.

If I were you I would have the 8omm inlet housing modified to except the 82mm TB by welding additional aluminum so that the wider TB will bolt up as if it were stock. The two inner holes at the bottom of the 3rd pic are the factory holes and the outer holes have been added to fit the larger TB.

Has there been any back to back dyno's that actually show a gain with a bigger TB?Like not with a retune just a heads up swap?
I just hit the dyno and finally used a dynojet.
car made like 500whp on the second pull and would of made more if we did a 4th gear pull on the first pull instead of 3rd.
I told him to do 3rd because Im used to a loading dyno and 4th gear puts massive strain on the car and thought it would be the same on a dynojet.Legit 4th gear pull would take close to 40 seconds to complete on my old dyno.On the dynojet it was over in like 6 seconds.
Next time Ill do a 4th gear pull on a cold blower in 4th for sure.
I think with a 185 pulley Ill break 550whp and thats with a stock TB
I had 597rwt on the 3rd pull in 4th gear and the owner said I would of broke 600 easy if we did a 4th pull from the start with a cold blower.
Its crazzy how much higher my car is doing from my other dyno that uses a loading dyno.I think Im up 60ftls and 60whp over my old dyno.

I thought all dyno pulls were suppose to be done in 3rd? if it's done right in 3rd you avoid the kickdown and if you dyno in 4th it takes so long due to gearing & avoiding the kickdown

the ratio thing really doesn't matter, the dyno compensates. I've dyno'd over two dozen cars in just about every gear possible and they all give near identical numbers. The only problem is when you have wheel spin or in turbo cars when a gear is too short and the turbo lag is more apparent.
regardless, I too am skeptical of the larger TB's making as much power as some say they do.

I already opened up the intake as much as I can with the airbox and python tubes but Im still on the stock TB.
on the dyno sheet it also says baseline vs headers and TB.Did you have the headers on before the TB?

and 35 degree air temps help also.
I might buy a 185mm pulley and see what I dyno,I think I can pick up 20-25whp going from a 178

Looks good but you changed the whole intake setup along with the TB on that pull.

The first graph was with the headers, the second graph was headers, 82mm tb, and intake. The second graph gained 37 whp if I remember correctly. The reason I didn't go with the stock intake because it wouldnt fit.

From what I can recall the 82mm buzz started with Angela's car at a private event when her was blazing down the track with higher mph than guys with the same mods with the difference being the 82mm TB. Maybe someone like Mo or Mikey can chime in as they were there that day.

It may make more torque initially because our cars are automatic, but it's usually just a small peak and then it settles. I dyno'd my E55 in 3rd and 4th and while I hit the top speed limiter in 4th, the power was identical all the way to 155mph. I haven't tried it yet with my current mods because the pull just takes sooooo long compared to 3rd. But all my other cars have been the same as well as every car I've tuned on the dyno.

Here is a quick comparison from when I had my GTI. One dyno was in 3rd gear and the other in 4th gear. This was on a smallish turbo ( I ran 6 different turbo setups on the car...lol ) and on pump gas.
Notice how there is only a 3whp difference and 14wtrq difference which can be explained from the turbo spooling slightly quicker due to the taller gear. In the E55, this doesn't matter since the supercharger will always have the same amount of boost regardless if it's in 3rd or 4th.
In my Grand Prix, being automatic, if I dyno'd in a taller gear the car would give a slight bit of torque as soon as I go wot and then it'll level out with the lower geared graph. I figured it was the torque converter stalling slightly higher due to the additional load. Any can correct me on this, but I've done dyno's in just about every gear ( even 1st gear on some cars ) and the numbers rarely change.
