Here's a pretty good read. I'm curious to the actual bolt ons used. I'm also wondering what truck was putting down 200 horses.

Some of the 99+ Vortec trucks have precats?

Huh. I agree with him for the most part... Except for headers and exhausts.

 

It could also be viewed as sales propoganda from the other side. If I were at Belle, I would do the same - "Yeah, all the bolt ons will give you nothing so buy our product"

Not trying to refute the claims and all and I agree on many points made (TB spacer and such) but with all I have seen in terms of headers, intakes and exhaust and actual dyno runs back to back by customers (not the producing company) with shown HP gains, although minimal in some cases, I find the "0" hp claims kind of suspicious. Belle has something to gain, the owners I have seen do dyno runs both here and in person had nothing to gain other than to see the numbers.

Propoganda in the sales world is no different than in the political world. There's always motivation and it is usually power or money....or in this case power FOR money.

Having said all that - I know that forced induction, hands down is the most efficient, reliable and proven bolt on but I cannot afford to break parts, swap transmissions when they fry yearly, blow up the motor, etc. I wish I could, but the dough goes to my 70 Chevelle SS

 

That is just like them to bad mouth something, trust me I know! Don't get me wrong, I love all power adders, even superchargers, but that docs is just crap, lol.

I like this statement, lol.

These powerplants tend to run in virtually optimum mode all the time.

That dyno data was probably a dodge, hahah, of course it's not going to make power. Plus, we all know you can't add up all those HP numbers like they did on the chart. The cold air intake will give you 16hp, but maybe on a stroked engine that is just begging for an aftermarket cai and not the stock setup.

Not to mention if they did come from the factory running optimumly then allen would be outta buisness. and im pretty sure everyone agrees that he brings real HP gains with those tunes.

 

I amell something foul .....

I think this is yet another lame paper by Belle. From what I've read/heard about them, this sounds just like something they would publish.

I will agree though, some bolt ons do show minimal gains, but on performance applications, it's what matters.

 

most of the kenne bell statements are more truthful than what you see advertised in magazines.It is much harder to get gains over stock hp and tq than it used to be when the factory designs were not as efficent as they are now. Intake and exhaust helped minimally on my 5.3 I dynoed my truck at stillen in costa mesa calif. The hpp3 made 4 peak horsepower over stock. At low rpms of 1200 to 2000 it picked up 12lbs of torque and 9 hp. I gained maybe .05 from a gms cold ram air calibrated maf ,lost a little bottom end with bbk80 mm throttle body, header s and duels maybe 6to 8 hp they are jbas volant ram air . so all that and a posi dropped stock 15.66 to 14.84 mostly from shift poiitss to 6000 and rev limit at 6200. then i put on a whipple, went 13.88 today I just go t back from kenne bell. they replaced my whipple piggyback with bigger injectors and their computer program. I picked up over 50 hp at the wheels over the whipple add on injectors. they did lower my rev limit to 5500 and shifts down to 5200 . I have not tested at the strip yet but hope the extra power makes up for the lower shift points and produces the same or quicker times. I will know in a few days. the proofs in the puddin so I am reserving judgement till I get some new track times.

 

(cough)(cough) bullsh*t
A simple switch from dino oil to syn produces more power.
An engine is an air pump - more air in more air out.
So a true ram air intake doesnt produce power - bull f'ing my ***
If that is true - why do it on production cars ?
give me a break....
Run you Kenne bell thru a stock air box and a ram air box and see which one make more power....
Snag - your right on this stinky pile

 

after the way kenne bell pissed on allen for no reason on the ss board, i have very little respect for him. this just add's to it.

 

Yea bolt-ons make NO power,I only made 297 rear wheel horsepower with just BOLT-ONS because I had a magazine in my glovebox with a Kenne Bell ad in it.
