  Good buy Cam lift at. 050 lift is a bit off but otherwise beautiful accurate in determining base lines. Maybe not a real dyno and should use a few tweaks for better accuracy but for $1.50 you cant search a better tool for the price.

  Travis Gustin: Good apk with room to grow. Very awesome apk. Lots of options. Probably the best apk of its type. Would like to see piston speed as well as more advanced options for players that understand it all should use (ex. Option to place in actual weights of pistons, rods, etc) to assist create a more accurate analysis. Also, possibly options to have dual cam specs when "VVT" is chosen.

  A Google User: Fixes create this the best! After the latest fixes for Galaxy Nexus and the addition of lobe center line and head cfm, this apk is the simply one of the coolest apks on the shop bar none. Replaces ALL compression calculators and is the best HP calculator there is.

  Steven Crawford: Beautiful good! Everything seems to be beautiful solid. Only add on I would recommend is dynamic compression ratio for those that have degree'd in their camshaft. Another than that, it's beautiful good!!

  Daniel Zuhlsdorf: Its awesome But should be better. I see you have the old school Chevy's, fords, and Mopar and a few tuners but... What about the fresh? The Chevy LS family of v8's and hate to say it but the ford triton v8's and the newer dodge's? The old school engines maybe more readily accessible but this works as a good program to go ahead and search what possibilities you might have with your current car. I have a 2000 Chevy Silverado with a 5.3 and it would be nice to have the various preloads for the rest of the the LS blocks.

  Jeremy Davis: Awesome apk Apk is awesome gives a lot of details provided you enter components correctly. Would be a five star for me except my 1/4 mile ET is stuck 13.64 @ 99.01 mph no matter how much HP or motor vehicle combo. Another than that solid. Fix this and five stars from me.

  bob Nuggunt: Its awesome It would be cool if there was a thing that generated a torquecurve so we know where most of the power comes from and where it drops off.

  Ethan Elliott: Nice! I'm really enjoying this!!! Its an good time assassin for a gear head! The only thing I feel like that would create it better is some preprogrammed heads and cams! Also would like to see 1/8th mile added in too. Another than that NICE JOB!!!

  Edward Behl: Good Apk yet would like to see more I do love this apk yet i may be a bit of a perfectionist but i would like to see more from this already good apk such as AFR control within the allowed range for each fuel kind like 15.7 to 11.5 for gasoline 11.2 to 7.1 for ethanol(e100/?e85?) 6.7 to 4.5 for methanol and 2.6 to 0.8 for nitromethane also fresh fuel types like butanol 13.8~8.9 isopropanol 12.9~7.6 and possibly a custom fuel option using defined fuel parts (the info is simple to receive) also the secure octane should still present even when using a fuel another than gasoline with an AFR affected effect. However the largest thing bothering me is the intake types they all seem a fixed flow rather than scaling with the number of cylinders or size of the engine for example i setup a really awesome engine for instance a four cylinder of 2.5Litre capacity and then wish to model the effective output of a V8 using the same cylinder dimensions just twice as a lot of cylinders yet my top end rpm goes down considerably when it shouldnt the intake could scale with the change not be same choking the V8 with the same intake flow as the four banger of identical per cylinder displacement just various quantity of cylinders total plz fix this

  Blake Jones: I like it I have a few questions about it though. Does it average the power loss from the crank to the tires? And are you ever going to add the Mopar 318 and 360 1992 and up for the rams?

  Broncos Fan: I like this apk and it works for a few engines, but engine rpm and torque curve is too strongly linked to displacement/# of cylinders. HP is a bit inflated on the 87-93 5.0 and no amount of adjusting to the head/cam specs can bring it down. You can imagine how far off it was when I tried to enter a 4.9 I6 lol

  A Google User: Alot Of Potential It really needs the option to input what your heads flow at .100 - .700 lift. It can't be accurate without it.
