torque converter robs you of HP by increasing drivetrain losses. And i wonder if valvefloat is an issue for u.

chrism400

Are you sure you didn't put the stock cam back in?

med_reject

HAHAHAHAHAHAHAHAHHAH!

(apologies)

you cant compare dyno numbers of a stalled auto with an m6. 30 to 40 rwhp difference is not uncommon.

pretty sure its the converter killing me its got to be its shot.its a 2400 slp stall.btw i went back to the dyno and locked up the converter and it made 335 at 5700 then i came off the ground so by 6250 no tellin maybe 350!got to be the problem!what do u guys think?

med_reject

335 and 5700rpm with a cc306 sounds completely normal. I wouldnt worry about your car.

red96z

well do u agree with the above post?and also maybe 350 by 6300 huh???

Thats sounds about right but just how high will the cc306 make power, I was under the impression they peak at 6? But 335HP is nothing to snear at even if it made 340 thats a lot better than before. I'd do somemore tuning tho.

red96z

what im trying to is at 5700 where i came off the ground it was still making good power i mean on a steady upward climb so who knows how much it could have made going up to 6300 with out coming off the ground.

The track will tell all you need to know.

You don't need to adjust the rockers with the car running. And you can do it cold as well.

Glad your numbers came back up.

once i decide between the edge converter and a west coast converter and get my new tune from bryan i will be heading to the track!

cc306 makes power all the way up to i believe 67-6800 rpm. when you're revving it up in that range is generally when you're going to pull the higher peak hp. and when revving that high, you're going to want Comp R lifters(875-16) to avoid valve float which will lose you more power.

red96z

i have the comp 850-16 lifters are those ok?

GR8RIDE_96

well, they're ok, but i'd step up to the comp R's if i were you. i know there are a few people who run stock lifters, but i think most of them are just temporarily running them until they can afford to get the comp r's.(from what i've read anyway)
i believe the stock lifters are good to maybe 6200rpm. so with the cc306 making power to 6700 or so, it'd be a waste of that cam to only spin it to 6200 and you'd be losing power spinning it above that with stock replacement lifters.

just my 2 cents.

red96z

would u want to run the stock bottom end to 6700 ?man i would hate to have to change the lifters out when they were just bought and installed at the end of dec. the guy who did the install works for comp sold them to me i had no idea!is it a must!
