well, do it again but this time let it run again and then check it just to be sure.
the car also has been sitting for a year and maybe only have about 200 miles on it since getting it running. |
Ouch, those numbers were cold? A hot engine (which is the way it should be done) typically yields 5-10 psi lower.
I don't think those numbers are from sitting. Who built the engine and how old is it? Honestly, I don't think I'd tune if those compression numbers are correct. Not much to gain (ie low power) and lots to lose. |

Not much to gain (ie low power) and lots to lose. Rich, yeah the numbers were cold as we couldn't get the car out of the garage to start it up. Motor was street ported by Pettit racing (from what the guy I bought it from told me) The guy said he only used it about 3k. then it sat there for months. I got it, sat for another few months. put it in ran it with twins but with massive boost leaks. turbos started to leak bad. Ripped it apart for the single set up and has been sitting for about a year and since we got it fired up it probably put about 200 miles on it. street tuned it to like 2psi so I can get around. (never tested the compression before the other day though so for all I know the motor might have been squatted out from the start) Well, I at this point, I do not have the money for a new motor or a rebuild, I am hoping I can tune it with this compression at least to some drivability. I am going to assume the risk is blowing the motor on the tune and breaking the turbo along with it! its either that or have a car sitting there that I can't drive. don't know. :( |
Were the pulses even? What kind of compression tester? Did you have the throttle completely open while testing?

Well I agree with goodfella man. It can be a lot to lose but, If it was me I would just let it run for hour or two. Then check the numbers again. Then do the test again. If the numbers are good after that, Let it cool down. Come out the the next day and do it again and see if they match.
The one thing I live by is never buy a used rotary engine. You never know if the guy is telling the truth or If he just doesn't know what he was doing with his car. I've heard all the excuses in the world man. Now if there is something wrong with it. Go and get your self a factory shop manual and buy the Pineapple racing rebuild DVD. Its not as hard as you would think. Do it all by the book and check everything twice and you will do a great job on it. |
Car is fine, numbers when up and it's running strong!!

Good. After letting it run right. Some times the seals will stick a bit when the engine has sat for along time. Even more so if you haven't really broken it in yet. What are the numbers at now?

Did not get to push the car to what I wanted, but happy its running and feels great! :icon_tup: |
considering I thought my motor was done, yesterdays dyno tune was great. did not want to push the car to much and ended up at 350hp at 12psi. not bad for pump gas with no meth or anything.

Glad to hear it is working out ok for you. Now to think; if you got off of your ass and installed the meth injection:scratch: what would it have put down?

well the reason I did not install the meth was because I thought the motor was not good and would not hold anything and would not have been pushing any numbers that need it.
What it could have done. I don't know. I would imaging at least another 100hp if I was pushing full boost and meth. but one can hope! but I am happy for now! so can't complain! |

When we got to speed1 the compression came out to 93 in the rear and only about 75 in the front, but the pulses on the front was not even so the corner seal might not be 100% or it might still be a little stuck from the long sit...

getting ready for Rotor fest this sunday! Car has been in my friends shop to fix my oil leak I was having (for a long time now) turns out my motor mount bolt issue was larger than expected, hope to have it figured out by tomorrow so I can get it all closed up.
Just need to figure out what size those damn bolts are and get them a little bit longer... Which I know will be a bitch to find locally! But I hope it can get resolved and Hope I can do a few passes at Rotor fest! |
had quite a few people in our caravan to rotor fest. left a little later then expected... but we rolled about 11 cars deep.
