Cool. Thanks

 

See if I can do a dead horse of a different color.

Again, my issue is simply loosing power after removing the Comp R's and replacing them with Morel lifters in an attempt to find a little more. Well....... we put the Comps back in and it's not the lifters.

So for what it's worth and Comp R's breaking aside...... the older Comp R's and the Morels dyno the same. The only difference is the Comp's like virtally no lash while the Morels were set at about .030.

 

Did you recheck the PR length on the Morels?

I was kind of expecting that your problem wasn't the new lifters.

One of those things that you think of after you've replaced them and put the intake back on. Na, blew it and forgot. We also put a Delteg ignition on with a fresh set of plugs and it had the same effect....... no added power. We're going to try a couple of other cams and the Morels will end up back in the car but so far it's a toss up as to which one is the best if you set them up like they want to be set up.

Honestly think part of it is the poor air quality but I'm having a hard time believing you'd loose almost 40 hp from air quality.Maybe there is something after all to those red Ozone alerrts.

Even replaced the intake as evidently there is some sort of pin hole from porting that was letting oil get into the intake. Took care of the oiling problem and my home porting of the intake produced the same power as one that had an absolute max weld n port job.

After I paid for a new die grinder, fed exed paper porting kit and a new carbide grinder........ figured I saved about 10 bucks an hour doing it myself vs letting someone who really knows what they're doing do it. Hell of a deal.

Were going to bring in a car with a documented dyno sheet done on the same dyno and see how it does. Might be the air......... Might not. We'll find eventually but for sure it ain't lifters.

Maybe I should start taking bids for the older version Comp R's as they seem to be pretty good.

 

I still need Scott to redyno/retune my car since I installed my 42lb injectors..Maybe we can put my car on the rollers since I still have my dyno sheet from Scott's..only thing changed was the injectors...maybe the dyno is inconsistent???
My comp r's are worth $500 to me I bought mine out of a shop in Houston called GTP about 3-4yrs ago..Maybe they have some left over from way back then..

Doubt Craig has them laying around, I sure know I don't.

Bret

 

Dyno's are very consistent........... car are inconsistent. So, may I take your bid for $500.00? Do I hear $510.00? Haba, haba, haba.

Scotts pretty accomodating. The problem is you made changes so your dyno data won't be consistent. We need apples to apples to see if the air really makes a difference or if it's just our inability to figure out what's really going on.

Fickle fricking cars anyway.

Trust me....... I hope it's the air, but I'm not banking on it. Lifters........ nope.

 

I would definitly check pushrod length if you are going from Comp R's to the Morels. The lifter body on the Morels are longer, not sure if the lifter plunger/cup is in the same height/location. I upgraded rocker arms, so I needed new pushrods anyway.



Nick

 

We didn't check the length but the dyno runs for both lifters are basically the same so if it's off, it not enough to effect the dyno. But your right... never take anything for granted.

 

left field fastball going for the jackass award.............
i dont know how knew the motor is[?] have you looked at your spring pressures? i reread you posts and couldnt figure out if you lost power just upstairs or across the board.sounds like youve got some time at higher revs,older springs might be wheezing, but if its only dyno time: didnt mean to bring it up, im fairly sure its not a PS motor that needs springs every mealtime.
