Modern Muscle (Va.) ported TB tested on dyno
 

Just wanted to give out some great news. I base lined my Magnacharged 10 Camaro SS, then installed a Modern Muscle (Va.) ported throttle body. The gains speak for themselves...just check out the graph below. The throttle response is sooooo much better/quicker than with the stock throttle body.

Just so everyone knows, we did NO tuning before or after the install. We tried to keep everything the same temp wise. The car baselined a little lower than the last time it was on the dyno, which doesn't really matter as far as what the gains from the TB were. The highest number the car ever made was 595rwhp with everything optimized...perfect weather, car cooled down completely, etc, etc.

Due to time constraints, we put the car on the dyno "hot" made a pull for the base line, swapped the TB (3 minutes) and made another couple of pulls.

So, what I take from this is the more modified or better breathing the car is the more effective a ported throttle body becomes. 25hp is quite an improvement.

:popcorn:

You will never see anything close to 25 rwhp on a N/A car.


Is the ported tb the same size as the stock one? Only ported?

LS3 car?

How many psi?

Any other mods?

I dunno lethal swears that a ported intake and tb work very well in conjunction with other mods.

On other cars ported tbs and mafs gave good upgrades.

It's debatable what gains you'll get on a n/a. Some will say none and the others will say 5-10. No more than that. A ported tb is more about throttle response. A pd blower car is different but it needs to be bigger. Just ported a tb on a pd blower car and gaining 25rwhp is suspect. I gained 25 rwhp with a 102mm tb. Much larger than a ported stocker.

Well any restriction you can remove in front of a positive displacement supercharger will show gains and even some boost increase. IDK about 35lbs of torque and 25RWHP though. That seems like alot for a 90mm TB.

That's what I'm thinking........

looking at the dips on the graph, that car has some serious tune/kr issues.

I agree to all, this is the second time they've posted a suspect dyno graph.

Where's Bo White when you need him? Does he have a beacon or something like Batman that'll draw him to this thread?:)

From a business perspective one would think if a company trying to break into the GM line like you said, would take it upon themselves to provide the most data and several tests (Dyno, Track) before the outrageous claims of one car. Seriously, I understand your in the business to make money but to enter the C5 forum with far fetched claims especially the NA car a month ago or so really turns people off. You have been in business and porting heads for thirty years, maybe it's just me but I would have expected more out of an introduction rather than going off what a customer claims on his own.. Facts and data speaks volumes. So on a side note all the NA guys should be able to put a 102TB on their cars and expect more than what you claim. Pretty sure the 102 doenst do much for a NA car and for sure not nearly as much on a stock car. In the end your first claim was dynoed at an "Independent shop" with a gain of 13hp and 17tq. Its a safe assumption that a 102 would make atleast 20 right? If that was the case there would be a lot more of them out there no matter how much they were. So, now that I'm done ranting and raving in the end all the camaro owners or who ever for that matter will spend their money on the go fast fix, but when it seems unrealistic the red flag goes up and they wont buy. I get it, there is an ass for every seat and some will bite for the sales claim but most will probably say :bs:
I said to much as it is, much luck in your quest. Sorry if I offended anyone, it's been one of those days.........
