I Thought Hybrid Intake Had better Low End???
I was at the frankencar web site and they post dyno runs before and after with their hybrid filter. I am assuming that the before setup used the stock air box, though I did not see it mentioned specifically.
http://www.frankencar.com/project_02_max_se.shtml
I printed the two dyno plots and overlayed them. When I held them up to a light I was rather surprised to find that power was lower (by 10-15 HP at 3000 RPM!) with the hybrid all the way up to about 4700 RPM (where the hybrid outperformed the stock box significantly). I e-mailed Steve at frankencar with this question a couple of days ago but have not heard back from him yet.
Do all after market intakes perform worse than the stock air box at engine speeds less that 4500-5000 RPM? Or is this not typical of other intakes?

well, it depends...look in the stickied post about temperature of intakes. i believe a regular cone intake works well for a five speed and a cai works well for an auto. i know cai suppose to eliminate the low end lost. i did the best of both worlds and got a cone intake and made a short ram tube for it.

At the following link I have a print screen of my before FrankenCar (stock airbox - 205fwhp) and with FrankenCar (K&N filter 210fwhp) as well as the FrankenCar without letting the ECU adjust (K&N filter 217fwhp) in the WinPep software. At no time is there a real significant loss, yet there is a noticeable gain in the upper end.

[the graphs have differnt scales on them and they will look different if you just priont them out and lay them over, i ahve the dyno jet viewer files someone and there isn't that kinda of a loss at all, sorry about the eamil also my SMTP isn't working.QUOTE]Originally posted by starcruzer

[i'll take a pic tomorrow since it's fixed AND lowered now. it looks so much better. i'm happy again.QUOTE]Originally posted by akrus
Steve, I beg you to change your sig pic. It's starting to hurt having to look at a banged up Max, especially in that colour.

You need to learn how to work with quotes.

The only way to compare the two plots would be to intersect from the desired rpm up to the line and over to the HP scale for each graph. Of course I wanted to do this but since there were no major or minor grid lines on the pictures, I took the liberty to add some. The results were just as you said, no loss at all, in fact there were improvements at almost every RPM (except for that funny dip at 4500RPM ). In any case, here is what I've found.

BTW, thanks Albert (Arkus) for the link to your dyno jet graphs, they support the data at the frankencar website (including the dip at 4500RPM...)
Sorry for misinterpreting your data Steve, but were all cleared up now. So when are you going to offer your intake for the 4th gens?

You are right about the scales being different (as if you didn't know that ). While the HP and torque scales stay the same, the RPMs are different for the two plots. My bad...
