Cam Gear tuning... -Dyno tuning-
We installed Adjustable cam gears, 60mm Throttle body, and made a heat sheild and tubing for a K&N Cone to match the MAF. still have stock exhaust, cat, and exh. manifold. but it dynoed pretty well... it's a Friend of mines 02 Pro 5, 5spd with 24k miles on it...
the stock runs with out the 60mm tb was 99hp 106lbft
stock with out the K&N Cone and heat sheild 97.8hp 104.9lbft
Single high flo cat and custom exhaust from enthuzacar soon to come.

That's great that you installed cam gears, but what cam timing did you use to get those dyno numbers? Also, did you test the cam gears or oversize t/b by themselves so you knew what gains came from what parts?
Inquiring minds want to know.

Nope.. ran the cam gears with the TB and K&N installed..
I'll get a pic of their settings tonite. the dyno sheet was sent to me by the dyno tuner about 2 hours ago.. we don't have the car back from the shop yet.

I tried retarding the exhaust, but our distributor is driven off the exhaust cam, resulting in ignition retard and poor performance. On the Protege the exhaust retard should help performance as well.

If there's some obvious, well-known reason why this can't be done, forgive me, I don't know that much about Probes.

Actually, this brings me to another Protege ignition idea I've had before... slotting the CMP and CKP sensor mounts and moving the sensors to fool the ECU into advancing the ignition timing.
After I get another vehicle to drive, I intend to try it.

Silly question... if you've got a distributor, why can't you just advance the timing that way?

The only problem is that the Protege's ignition timing also works off the exhaust cam, it just uses a CMP sensor rather than a distributor. If you move the exhaust cam, the CMP sensor and CKP (crankshaft) sensor will be out of sync and the ECU will throw a misfire code.

You might wish to look at a J&S Safeguard or possibly one of the MSD units. Some of those are capable of advance and retard independent of the stock ignition.

Is that with the stock cams, J-spec/MS or the Sunbelt cams? I'd like to know what the numbers are on the Sunbelt cams if thats what they are.
The graph looks to beat the 99/106 numbers all to **** too. Wht's up with that?

I'd really like to know the numbers of their cams, and why the dyno graph says 117.9ft-lbs but you report only 106. Let us know how it turns out with the head and cams at least.
Good chop on the belt cover BTW. Too bad that hall effect had to be retained.

One other question for 1FST2M6... to tie into our discussion about the CMP sensor, did changing the exhaust cam timing a little bit (like 1-4 degrees) actually light up the MIL and change the ignition timing? It's occured to me that the PCM might tolerate a little bit of leeway in the CMP sensor position to accomodate manufacturing tolerances. Also, the PCM might primarily use the CKP sensor to set the ignition timing and only use the CMP sensor as a check, in which case the timing might not be affected either.
Just curious.

sunbelt performance ones..
and their larger TB as well...

how much if you dont mind was the TB?.
and what is the size?
and do you have a contact number for sunbelt?
thanks in advance
