Low dyno numbers
Re: Low dyno numbers
I stopped down after work and asked them about degreeing the cam.. They didnt think that was the issue and were leaning towards the "chirp" in the motor.. I saw the thread where 15hp was gained w/ the cutouts.. I would hollow out the cats in a heartbeat.. Looking forward to hearing what they find when they drop the pan.. After inspecting the oil filter didnt seem too bad?? I understand any metal in the oil is bad.. Seems like some is to be expected after all the new parts.. fingers crossed.. I want the car back bad.. To warm to be driving a winter beater..




Re: Low dyno numbers
I did the valves originally with motor running 1/8 turn past where they were clicking.. When I dropped car off at tuner I asked them to adjust, they did them using a dial indicator..
Re: Low dyno numbers
they pulled pan and 3 rods all shot.. pulled 1 main cap bearing spun.. said it looked like it has been going on for a while.. The low oil sensor had layers of metal on it..
Re: Low dyno numbers
Well that's no fun. Keep the heads, get Lloyd to spec you a bigger cam,and enjoy the new stroker.
Re: Low dyno numbers
I doubt the heads or cam got jacked up, have them inspected and re-install. Don't change rocker ratio, don't buy new heads or any of that malarkey.
Re: Low dyno numbers
Thanks for advice.. They cylinders still had quite a bit of criss cross when I had the heads off.. What are you thoughts about doing a ball hone and just re-ringing original pistons?
Re: Low dyno numbers
The last motor I built we checked both the bores and pistons and they were within tolerance so we honed and re-ringed the motor. New Mahle rings are lke $65. If you're able to do that it'll save you even more money. If you're N/A at not at radical power levels I think it'd be a good move, especially on a budget. We had the crank turned and did ARP bolted PM rods. The motor has a XE503 cam with GTP heads and runs like a top in a C4 Corvette.
Re: Low dyno numbers
Joe is right, don't do this. The camshaft was designed for a certain rocker ratio, this isn't 1974.
Have you ever had first had experience or CC'ed some of Lloyd's heads? I've done a few and you're making quite the accusation to say they are off by 25cc and don't flow the numbers they claim. I could understand if Lloyd was a snake oil salesman who just peddled junk to feeble minded folks, but he's been around a long time, does excellent work, and supports this community year after year. You're clearly a novice and we don't need the blind leading the blind off a cliff here [parking brake and 1.5 rockers].

The OP claimed he wasn’t making the power he hoped for or at least on the dyno, there was nothing about engine troubles till latter. He indicated nothing other then his mechanic hearing a chirp noise. I’m not here to participate in your sausage-wagging contest, and yes, my parking/break pad was stuck on one side where it wore down to the point that it could have been used as a door wedge.
