Saw this on rennlist...

 

haha...23hp....be lucky to get 5 IMO....

 

The intake adds 3 hp and the carbon fiber top adds 20hp

 

Maybe they forgot the test car's ECU was flashed,LOL
evoms only claim 10-12 HP, but 25HP with ecu flashed..

 

i'm amazed they can get away with making claims like this. i know all the manuf. do it, but this is just silly.

 

Total BS.

Neil

 

Is there no honesty left?

 

I know 23hp seems pretty high for a NA car but has anyone installed it and confirmed that it definitely makes less power than what's stated?

 

must be at the crank. i didn't see 23 RWHP

 

speaking of BS, there is a guy on here that said he bought a set of headers from you (Inox or something like that) for his 996. he claims he picked up 56 crank HP just from the headers.

do you have any idea what he is talking about Neil? he says his car is supercharged as well.

 

WTF thats BS, I am expecting a gain of 2-3hp thats all

 

I was both shocked and laughing at what K&N Engineering were quoting on their website regarding the HP gains from their bolt on air intake kits.

Here are some of their HP figures they quote,

2005 Dodge Ram SRT-10 19.12 HP

2001-2005 BMW M3 18+ HP

2006 Dodge Magnum 21+ HP


So what do you all recon ? I personally believe that you cannot gain so much power from bolting on an air intake kit on a NA car. Yet, you can expect more gains on big displacement cars over small displacement cars. Nothing could beat the HP gains of an intake filter on a Forced Fed car.

 

The cars you mentioned probably would gain that kind of hp. It's all about volumetric efficiency of the engine and the resulting hp/cid/ld. The m96 motor is working at about 85%ve now(almost 100hp/ld), so you can't expect huge gains. The motors you mentioned are really bottled up, and are only at 60-65%ve at best. If your std 350ci/5.7lsbc v8 worked at 85% ve, it would be making 570+hp, instead of 275.
It's all about how well a racing engine utilizes a given volume of fuel, check out Bill Jenkin's book, "The Chevrolet Racing Engine", it's a bit dated now but really goes into the basic physiology/engineering of a racing engine.

 

If you look closely though you'll see it's not 23 peak HP hence that's a bit of a play on words and creative advertising...it's 23hp at 5500 rpm that they're claiming. Looks like peak HP gain is virtually nil. Still the dyno graph doesn't look bad from 4500-6500rpm.

 

Looks like I'm going to get this and do some dyno runs for you guys!
