So what would be the compression diffrence between the mahle and the speed pro power 20.1 or whatever it is compared to the mahles?

 

On A 0 Decked LT1 4.030 with 54cc chambers and a .029 gasket you looking at 10:1 with the JE -21cc pistons. The Mahles are -31cc and put you right at 9.03:1 on a 3.5" stroke.

 

What kind of compression are you looking to get out of the -26cc mahles?

 

Between 9.2 and 9.5 depending on what my actual deck height is..... 9.2 is IF I have a deck height of .015, I can get lower (9.01) if my deck height is .015 AND I go with a .039 gasket instead of the .029.. My goal is to get between 9.0 and 9.5

 

Got a part number the only thing I could find on their site was -26cc and nothing from 909. And CNC-Motorsports website isnt working for me !!

 

yeah i couldnt find them either.. i will probably just get the 5.7, 3.75, -31 JE's

 

What number do you reach mahle at? I would like to know when they plan on shipping these.

 

828-650-0805

they told me around the end of the month. let me know if they tell you something different

 

4 to 4.5 weeks

 

thats a little lonnger than what they told me....

Did you like there hold music

 

I made up my mind that im gonna wait for these to ship. I still gotta wait for the machine shop to do all the work they are gonna do for me and alot of small little jobs to get this thing ready so for the price compared to custom pistons. Im waiting in line! Keep me updated if you hear anything else.

 

Called them today to see whats up and Jason was very helpful! the pistons are scheduled for production 20 days from now BUT he said that there was a possiblity that an engine program could pop up and need to be put in front of these. (800-900 pistons =more$ than 100~) he said he did see that there were some of these pistons on back order and that helps to move them to the front of the line.

I also asked his to send me a screen shot of the cad/solidworks drawing of this actual piston.

 

Ya I cant wait that long, our cruise night is in june.

 

Just got word from Jason the engineer at Mahle that these have been manufactured and are ready for shipment! ill post pics once I get them!

 

So how sweet is this Jason emailed me today saying they are ready to go and I get home and this is what was waiting for me!!!
