It's not that engineers don't want you to understand, many times you just have to have an extensive background to understand the reasoning behind things. Thanks for the posts, as an engineer I actually appreciate the physics behind it

Basically what it's doing is he's taking formulas you learned in school and going by known values to determine the ideal temperature of the air entering the engine (blower outlet). Since that assumes 100% adiabatic efficiency, he's accounting for that in the efficiency calculation where you can assign a percentage probably taken from previous experimental data and assign it to change the ideal Temperature into an actual temperature. Using THAT temperature into the density ratio using degrees in Rankin (R).
Most these models are looking at the engine as essentially a big "air pump." That explanation above in his post is pretty good for generalizing the way the blower makes the power and the ability to show the % increase in power. |

Yeah........What he said..

It gets more difficult if you start trying to explain where certain things come from but for now just believe the formulas. Basic math after that

Good enough for me. I'll just take the word from the engineers

So what recommended psi will the KB 2.8 base kit be running at? To get the higher hp out of these, at what point do you need forged internals and at what psi to be on the safe side? Sorry if this has been asked already - the engineering talk has my eyes crossed

all i know is as far as the KB kits for the c5's go they werent performing like they stated. lots of restrictions in the intake i believe, its been reworked twice i believe and still wasnt performing. lots of KB kits sold and i have yet to see a track proven car, or one hitting 700+whp on forged motor.
personally i wouldnt buy a KB due to horrible customer service. no e-mail replies and contacting them by phone they show no interest in helping if they dont have a kit available already for the car they wont help. thats why whipple and maggie's will always be first choice, customer service OWNS. |

100% inaccurate.
There are more 700rwhp KB GM cars tan I can count. Yes, the original inlet design was horrible on the C5. Hence the reason we have spent years, along with 10's of thousands of dollars correcting it. The new inlet is just as solid as the mammoth for the Mustang. It flows 1602cfm. We completely changed everything. There is not 1 thing on this kit that shares similarity with the C5 Corvette. You are correct, back in 2005-2006 KB was having horrible issues with their phone answering skills. They were Ford guys, what did you expect... But since that time, KB has begun pretty much sending all tech questions to me, and I handle them. I have already received a few from this board today who called them. But getting tech issues handled in a timely manner with a KB GM car, is a thing of the past. Maggie has great cstomer service, I wont deny that at all. But when our customers are sitting at the end of 1320 feet, Ill be sure to have them on speed dial so when the other car shows up, he can b!tch to them as to why he spent the same money, and got his booty handed to him..

but yeah i'd like to see these 700+whp KB cars LSX powered, with motor specs, vids, dyno sheets. and hell the super fast seat in the pants crazy insane 1320 vids, that you claim. Last edited by nfamous209; 01-13-2010 at 01:38 AM. |
