too bad you can't take full advantage of the compression with bigger cams

1.5 · 08-21-2012, 01:02 PM

Or enjoying all of that powaaaa lol ^

Nanoss22 · 08-22-2012, 01:53 AM

Sorry i was specting to have the numbers to and for the moment i dont have the time to go and do the dynopull the work family and the college got me crazy and yes the engine is running good no problems for the moment the car feel very diferent when i step on it so dont worry i will gave u the numbers and some videos of the dynopull... So be pacient

taman86 · 09-16-2012, 07:13 PM

So any update to this? Still running? Dyno? Also I was wondering what engine managment you are using to run these. Stock, piggyback, or standalone? Where did you souce these from, new or another engine.

ilikerice · 09-16-2012, 09:53 PM

we are all still waiting for some kinda update on this one..

taman86 · 09-18-2012, 03:36 PM

does anyone have this guys number and give him a call. I WANT UPDATES!!!

I'm guessing he blew up the engine. That is way too much compression to be running on pump gas and cast pistons. To run as much compression as he had you would need forged pistons and run race gas. Mother wise you would not be able to control detonation. Of course, he could prove me wrong by posting an up date, but physics predicts that he won't be doing that.

You sure that the motor would gain that much power from a 1.5 point compression ratio bump that the cast pistons and stock rods would crack and pop?

Worst case you need 94 octane.

jetblast · 11-02-2012, 12:50 PM

Don't forget the toothpick con rods.

ilikerice · 11-06-2012, 05:40 AM

@Viperoni
I dont think its the "power" that he is referring to that will blow up the motor, but the compression itself and not using correct precautions. We will never know because OP hasnt updated

fast2882 · 04-06-2013, 10:06 AM

Hello there, any update ? dyno result maybe?

Golddeenoh · 04-06-2013, 11:26 AM

what would go first the cylinder walls or the connecting rods?

fast2882 · 04-06-2013, 02:01 PM

maybe piston hit the valve

Possible.. Would def want to clay before starting the car.

A lot of this is repeat from other threads..but seems very feasible:

The most I may need to change when running 11:1 compression is 91 instead of 87 pump gas, besides some EM. But even then....I run on 87 now...at the supposed static CR of 13:1 or dynamic 11:1.

Golddeenoh · 04-06-2013, 11:10 PM

i was referring to should it function what would stress out first. valve clearance would be the first issue maybe a shim gasket to gain clearance and lower compression ratio while also adding block guards might work great.

fast2882 · 04-07-2013, 11:53 AM

too bad the project isn't work, i still really curious about the result if someone can swap this piston and have about 12:1 compression ratio in 1nz-fe engine. toyota 1NR-fe engine series have 11.5:1 compression ratio, so i think actually it is possible to have 12:1 too.

BEEF · 04-07-2013, 12:27 PM

I think 12:1 is possible and even 12.5:1 with premium gas. the prius pistons are 13:1 so it is pushing it.

MicroImage has higher compression pistons for sale but i don't know of anyone that has done it. his 9:1 pistons are very popular in the boosted community.
