CR Calculator

Please update with more sohc F series like the F18 and sohc F20 stroke, rods, pistons etc and the option to use USDM and JDM spec K20 pistons in F series would be nice.

Cant use (-) for piston cc.

Missing a lot of information. If you have the specific information, the calculator seems to be fairly accurate, but it's missing information for a lot of different parts. If it were a general purpose calculator, I'd give it for stars, but as a Honda specific one, it loses another star for the lack of information.

Doesn't show any of the drop-down lists on my s7 edge. Messaged developer about this months ago, still not fixed. Works fine from my Note 3, however. Both are completely stock devices

I wish I had the resources to put this to use in more than a destroked d17, but I've played with it a lot. I'm not really worried about the engine specs being right, the math is at least good. Only complaint is that I can't seem to input a negative number for a piston dish, been a problem when playing with turbo engines, but hasn't stopped me.

Needs negitivee button fixed

K24 info is dead wrong. A1 pistons are -10.5cc, A2 pistons are -4.1cc, and Z3 pistons are -1cc; head volume is 53cc. I also can't input a negative value for dished pistons.

nice app Good job

Improve app

The b18a stock compression is 9.2:1 and this app says it is 9.6:1????

Good enough

Perhhh..

Fantastic!

Nice app..

Fantastic!

What about j and c as well

Makes life easier

First use, changed a gasget thickness on a b series... Software quit.

Still cannot manually make a negative dome volume for the pistons. Will rate higher once fixed.

Good app missing just j series and c series motors

It claims a stock ls is 9.6:1? Ha ha ha couldn't be more wrong. Maybe with a hotter piston and some decking/milling. It contradicts information given in one of his other apps. fix it or take it off the market please

The information and cross-referenced specifications match up. I recommend it!

Where is the ew series or even a d15a3

What about j and c as well

What a handy tool! Great for determining what route to take on you're rebuild. Thanks Peter!

Needs negitivee button fixed

Works great I use it quite often

Everything I've used is accurate Thanks for the great app!!!

Cool rebuilder's supplement.

Improve app

Fantastic!

No not really. I like it and use quite often. Works well, and makes for easy showing to costomers what to put in their engines.

Did some cross referencing and the H/F information is right on.

Works fine, but need to cross reference some of the data to be sure its accurate DROID X

It wont let put in a negative number for piston dome. Fix that and it is a five star!

Great app only one problem It wont let put in a negative number for piston dome. Fix that and it is a five star!

It made me blow my motor! No not really. I like it and use quite often. Works well, and makes for easy showing to costomers what to put in their engines.

Hmm First use, changed a gasget thickness on a b series... Software quit.
