Real world hp gains with 76mm Pulley, tune and headers?

I was wondering if any one you did some sort of before and after test that shows real world hp gains with a 76mm VRP pulley and tune along with a set of Eurocharged headers ?

This is basically what I did on mine so far and the nearest Dyno is about 5 hours away....

edit: it is 76mm, not 86.

Did you try the butt dyno? An 83mm and tune only registered a substantial difference to mine. Numbers are nice, I am pretty sure there are dynos floating around of these (again assuming you mean 76mm as I haven't heard of an 86) but they are only numbers. And it doesn't mean that you got the same increases with the same mods either, there are a huge amount of variables. The only meaningful thing is to do a baseline on your own car, then re-dyno after the mods. Or 1/2 mile times, or some sort of other acceleration test you standardise for yourself. Something you can test without driving 5 hours if you have somewhere long and straight to do this.

Published numbers are +50-55 for the tune and 76 pulley, and about +30-40 for the headers. While staying conservative, car should have 550 crank +/- in principle.

Im debating weather on not I should go with a larger TB and larger cooler as well... would that give any significant increase in hp or it would barely be noticable? Having the larger tb makes be wonder about drivability... heard some negative things.

Cooling is good. Read through all the TB threads, some are a few pages. I would never even attempt one after reading those but decide what works for you. Some people have it working perfectly with minimal fuss. Others had months of issues and never resolved it. I can't find it now but I thought I saw someone dyno a 10HP gain on a fully modded car between the stock and aftermarket TB's.

See my thread recent updates. My 83mm + tune numbers are very close to what folks have already mentioned in this thread.

I have an SL55 with pretty well the works which can be done externally. I also have an E55 with ONLY an 83mm pulley and a Lawshee tune. My butt dyno says at least a 50rwhp improvement if not more and my V-Box concurs. With the stock exhaust it feels almost as quick as the SL55 without all the noise and bluster. A 76mm pulley will not do anything more than an 83mm pulley UNLESS you attend to the cooling requirements. Put on an 83mm pulley and get a tune from Anthony and you will be amazed. Just doing that will get you an 11sec 1/4 mile. I have a new set of shorty Eurocharged headers for sale if you want to get loud.

Good tip thanks. Did you have him do the shaft grind also or did you do it yourself? (I have done mine but I was not near as aggressive as I could be, scared of messing it up) What did he end up charging for the work?

Sounds like the way to go. Marginally smaller, less issues, less money. Did you open your snout up to 79mm also?

Throttlebody will be your favorite mod you do to your 55k hands down.

The throttlebody threads make it seem like they are a gamble. But with our bolt on plate we have so few issues its almost non existant. Less than 5% of the throttlebody kits we sell we hear the customer is having an issue with hiccup or lean spike. Its typically traced back to a leak and when no leak is found, they can be fixed in the tune.

well i have one of your snouts an there are zero leaks on my car and no one could get mine to wk with a bigger tb. I had tony try several different tunes as well as jerry. I sealed the tb, supercharger, and every other concieveable gasket numerous times using differing methods sealant, copper spray, nothing, and always cleaned the surfaces perfect. An if it were a leak mine wouldnt have gone away just by going back to the stock tb. I think some 55ks dont respond properly to the bigger tb. Dont get me wrong i loved how the car worked with the 82mm and even wanted to do the 85mm but unless someone wants to prove it to me id bet money it would happen again on mine.

You might say favourite mod being a seller of such a mod but unless you can
-provide unbiased evidence that it results in significantly more gains than has been shown on back to back dyno in the link above
-and explain why some of the most knowledgeable and talented owners here still can't get it to operate smoothly
Then that is a misleading statement. I am usually a cynic sure, but I actually want this mod to work perfectly every time and produce the stated HP so I can do it myself.

This. With an 83, larger heat exchanger, and China long tubes, my IATs can easily hit 130+ F on an 80 F day by the end of my first pass in the 1/4-mile. Pretty confident I'd be slower if I just pulley'd down without adding some significant cooling mods (ie; trunk tank + wmi). As it is, with my listed mods + shelf EC tune, the car runs extremely consistent 11.9's @ 121-122 mph (60-70 F ambient @ 300 ft above sea level). This is on 100% summer street tires cutting 2.0 60 fts. 93 octane gas. Depending on what bone stock traps you believe (anywhere from 113 to 116 mph), that's a good bit of extra power considering we're talking about a 4k lb sled. With proper cooling mods + 76 pulley, I can see 125 mph traps being within reach.

Legit street cars just posted a video of how he got his car to adapt and tolerate the 82mm throttlebody


Check it out.

I think you mean throttle body and no he didn't. He got the 74mm to work properly again after getting fed up with the 82. Then he tried the 82 again and it was better but still not working perfectly.

Not to mention this is not the same problem that alot of us are having. My 82mm worked amazing ... powerful .... flawless round town an wot. The lean problems i had were under light throttle on freeway an out of nowhere hiccup n lean mode til i cycled the key.

now i had replaced every single gasket, copper sprayed, and even siliconed some of them, replaced every hose and even epoxy filled the plastic plug on the back to be sure. I had it smoke tested at 3 different places with no leaks being found. Not to mentioni simply removed the 82mm and adapter an put the 74mm stocker back on with the old gasket an hiccup an problem free for monthes now so if i had an air leak it woulda shown with the 74 as well as the 82.
