the key here is proper hammer size selection

Awwwwwwwwwwwwwwwwwwwww, it's cute!

Are you running e85? If so it will make your oil in the catch cans a little milky sometimes, also under the filler cap.
The air is sucked out of the drivers side and into the passenger side. You want to put the catch can on the drivers side hose.
SoB, i could have sworn I read to put it in the passenger side!! dangit

well, bad news. no knocking showed up in the logs and i was def tapping pretty good on the engine.
also as an added bonus, after some significant time searching the internets, i believe MMR sent me 18cc dished pistons instead of 11cc pistons, giving me 8.8 instead of the 9.8 i asked for. unfuckingreal
Here is my sherlock holmes investigation laid out. I called MMR - they said they have two dished pistons for my 3v. 11 and 18cc. They also told me they have "no idea lol sorry" which would have been sent to me, you'd have to look at the piston itself. COOL
So Lito sent me a picture of a -18. I then found a picture of a dished 3v piston on the internet that looks different. Look at where the inner diameter meets the printed writing on the pistons. What would you think?
I mean a lower cr of 8.8 isn't the end of the world but hot damn, talk about wtf MMR
Litos -18's

Sucks about the knock sensors. I wonder what's going on there.
It looks to me like you have a 18cc dish. That really isn't the end of the world if you're staying on pump gas. If you had let's say 9.8:1 compression you would probably run out of octane spinning the blower as fast as you are.
You're still probably going to make 650+ and that is a lot of power for a 3v with a 2.3L on pump gas. That's right at the high end of the range. Actually I don't think I have seen 1-2 other cars putting down more than that. And the ones that did were just a little more.....or an R-Spec which is a completely different ballgame.
Like the others said 8.8 isn't the end of the world. It's more than a stock Terminator or GT500 has. However, if you somehow got the wrong compression height it would be a significant hit.
Stock stroke compression height is 1.220" with stock 5.933" rods. Stroker pistons with a 1.200", 1.150", 1.100", or 1.050" compression height would kill your compression.
It happened to a friend of mine. He had a shop put the motor together and they got stroker pistons instead of stock stroke pistons from dss. He was down on power by a whole lot. It was bad enough that he tore the motor down and discovered his pistons were sitting in the hole an extra .170" or so. Once the pistons were changed out power came back to where it should of been.
Have you looked at any images of their stroker pistons during your comparisons?
Well my end game plan for the engine was always to eventually run e85 so it's kind of lame but yeah, ugh!
Well I haven't even thought of that. The kit does have a stroke to 4.75 but I'm pretty sure it comes from the crank as it's a 11-12 gt crank
So they should have a coyote compression height if it's a coyote crank with 5.933" rods.
By any chance do you have the specs that came with the kit and if so what do they list the piston compression height at? Just wondering how they set it up. It would be possible to use 4.6 stroker pistons with it but they would still be sitting in the hole more than ideal.
Dude, this completely sucks. FUCK MMR!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Right. Holy shit. Oh well, it's on me really, I should have measured everything before install. It's a learning process! Should have just bought Bruce's car and called it a day haha.![]()

Fuck it, get it on the dyno and see what it makes. If/when you switch up to e85 you can worry about it then.
Or you could put an R-Spec on there with a 3.4L Whipple. It doesn't matter what your compression is then!!!![]()
I just skimmed through the whole thread. If I understand everything correctly it's making a whole lot of power and plenty of boost, right? As long as it runs well and makes more power than you want everything is ok.
Try to disregard some of what I said. Even if the wrong ch pistons were used all it's really going to do is lower the compression ratio. As an example the 5.4 pistons sit over .100" in the hole and the motors run just fine when boosted. It affects power output na a whole lot more than it does with forced induction.
The odds are that everything is as it should be with the motor considering the highway speed burnouts.
