BurningRubber said:Well after reading both of those tests and realizing the test car allready had longtubes, x pipe and catback, and it still only made 7 hp it seems like alot of money for something thats not gonna make 7 hp on a stock engine.
Think the money would be better spent on U/D pulleys or exhaust? For 430 bucks for the Accufab plenum and t/b I could buy a UPR X-pipe, two Magnapacks and dumps off ebay, and nab the Steeda U/D pulleys.
Even though it doesnt make as much power, the C&L unit is still appealing... For 120 bucks it is still a few HP, which is hard to beat now a days.
I think it proved that the accufab also flows much more air than the ones tested. great mod if you decide to do F/I in the future. I have not been able to find any flow data on BBK the GMS or the PP plenum so I didn't buy it..hotdog71 said:The only thing the test proved is that a 75mm TB/P make more power then a 70mm set-up !!!!
edbo said:Get the BBK underdrive pulleys. I got them for my '98 GT for like $130 from Summit Racing and the results were pretty noticeable, even on that ol' pig.
I have heard that the steeda udp set has a harmonic balancer.BurningRubber said:Arent they the piggypack kind though? I was told a few times that it was riskey running a piggyback set of pulleys on a 4.6 due to it causing harmonic vibrations and destroying the inernals of the engine. I was also told that piggybacks on 5.0's are fine since they are more inernally balanced or something.
If they replace the harmonic balancer than its all good is what ive been told.
Is that ass backwards or what?
The BBKs are NOT piggyback units. They're aluminum billet units and I never had an issue with them. They also look very nice installed.BurningRubber said:Arent they the piggypack kind though?

I got it about 11/2 years ago after read an article in mm&ff. I cant recall the phone # to his shop, but if u do a search on modulat depot/plenums, it will show up in some of the posts, as well as an article about his setup.BurningRubber said:Ok, I read the tests that Falcon Guy had mentioned. The most HP gained was with the Accufab plenum, and Accufab 70mm TB... Why didnt the 75mm TB make more power? Would it be better to get a 70mm TB instead of the 75MM one..?
BigT... Where did you get that setup from? Thats a very nice price.
javsvt said:I got the professional products TB & plenum. It is really good quality, I had no problem with the installation with the exception of the cruise cable. But all in all it was easy to install. I thought it was a good buy, you get a few less horse power than the accufab, but only 1 or 2 hp. I think its worth it. I felt a difference in the in acceleration. I dont think its worth spending all that money for a plenum and tb, for only 7-10 hp. I paid $250 for my combo. Im happy!
javsvt said:I have not seen any proof, that is why I think it is a good buy. For the hp you are getting on these combos, I think its not worth spending all that much. Just my .02. If you could find something less than go for it, and let us know. That is how we learn what is a good product. Im just responding to his professional products question.
