cam gears

[twilightprotege]

well they have arrived.

they are installed. 8 degrees retard on the intake, 4 on the exhaust.

idles well so far from cold.

then - the engine got warm and i revved it up to redline. felt great, but then when i went back to idle i heard a rubbing sound. i reckon the belt has just moved a bit or, the cam gears rub the head cover...but i'll check it out tomorrow night.

initial impressions are : gee the pick up is quick

more to come this time tomorrow...

Sweet. Dyno?

 

[twilightprotege]

not sure yet. the reason being is that i'll be getting a full exhaust (2.5") within 2 months. i'd get a dyno run and then i'll have to get it again. but when i get the full exhaust i will have them dyno tuned. THAT will be very interesting!!

aim with the exhaust - 140whp+ ... most powerful NA P5 yar???

 

[Mike R]

I can undestand that. How did you decide on the settings?

Get that exhaust and get it back on the dyno. You might just be!

I will be impressed with a Dyno. But, so far, you have done a good nice job on your car. Keep it comming.

Im questioning myself, how would I setup the cam gears for my turbo.

Where did you order it?

I know SR Mortor Sports has a set of cam gears out now
I would like to know how to set them up on a FI application too espeshally because of the Mazdaspeed/J-spec cams shafts i have

You would probably see gains if you were able to retard the exhuast cam 2-3 degrees. Turbo cars in general don't like overlap.

[aftershock63]

yeah I can see the logic in that, good thinking! Does anyone know how many degrees the stock over lap is?

 

[igdrasil]

yeah...I was searching for that info

-3 deg exhaust
+1 deg intake

thats on a supra setup

 

[ARunto]

yeah I can see the logic in that, good thinking! Does anyone know how many degrees the stock over lap is?

I would like to know as well...maybe someone who is building a motor can degree them for us.

the cam gears everyone is selling is made by sunbelt. i bought mine through propartsusa.com and had a few issues.

igdrasil - you would want to prob advance the exhaust 2 deg and retard the intake 2 deg with stock cams...

ARunto - you had it the wrong way around. there's a thread where we discussed the cam gear adjustment at length about a month ago...

the stock overlap would be negative @ 0.050" (where most of them are measured. even with my big duration cams, i only have 6 degrees of overlap (cam event) or -1 degree of overlap (valve event).

Glad to hear things are looking up. I keep waiting to hear from those guys about what's going on with the cams. Tried calling again today, still waiting....

 

[twilightprotege]

well all is fixed. i just added a very thin washer between the valve cover and the cam sensor. car runs perfectly.

initial impressions - mid range up feels stronger. redline is much better...probably around 5-8whp i'd guess

really need them dyno tuned, but i'll wait til i get the exhaust.

 

[akhilleus]

Wow... u r running a timing retard thats almost as big as mine. I would have thought that u would have a lower retard on the intake. But i am sure it has become quite quicker. I bet with perfecting the timing further u could see 10-20whp at least. Good job. (2thumbs)

 

[Javo]

NICE N/A all the way......Much respect to those who go N/A, the true tuning. How much you paid for the gears and was it hard to install.

 

[twilightprotege]

i paid $290 through a GB on here.

install was pretty easy for me. probably a difficult beginner's job.

ark - yeah i needed so much retard to bring the powerband down a lot. me thing i'll probably have to retard it more...only the dyno will tell...

 

[flat_black]

Awesome! Can't wait to hear the dyno results. =) Those things'll help out your aenemic low end once you hop on the dyno and start tuning. Awesome work, man. You're an inspiration to all us N/A folk!

 

[twilightprotege]

thanks man!

 

[Mr. Win]

awesome man im holding off on myinstall till i get all the cash together and get those gears. then ill do it all at once i think im going to install it myself... Ive been reading uo in it and i thnk i could do it. any suggestions on whati might need besides that im going to change the head gasket.

 

[twilightprotege]

all you really need is time. it's pretty easy. just take your time. follow the workshop manual and my how-to on here. oh, most importantly, have a torque wrench
