5800 ft according to my gps

 

Well, I got 0 power from cams, and the alky is equivalent to running race gas, which I was doing before, so I have no net gain in mods/power from when I ran my 12.000 at sea level.

 

So since you gained "0" power, where are you figuring mid 11's? Those 12.000 runs were about as good as they could have been with that amount of power.

P.S. Different Cams WILL change the engines powerband, in fact your cams dictate it. Unless you swapped stock cams for stock cams its hard to believe.

 

I didn't say I would hit mid-11s. I said I have the MODS for it. Unfortunately, I gained no power from cams. The power curves were identical with no change whatsoever other than 200rpm later spool. We are still trying to figure out why. Last night, I checked my cam timing, and it was perfect, so then I checked my compression, and it was right on as well. Either my head is just messed up, or the stock turbo is totally maxed out up here.

 

sorry to go off topic but you shift like a damn madman

 

Can someone give me an idiots run down on shifting? Why do you consider his shifting like a madman? What is the definition of short shifting and why would you do it or not do it? Is it the same as "speed shifting"? Never could find a good explanation of all this stuff. Sorry for the newb questions, haven't raced my Evo (or any of my other cars for that matter). Took my '98 Cobra to the track a few times, but just shifted quickly (but still what I would consider normal).

Thanks

 

I have seen many cam installs up here and all net a 20-25whp increase and a similar if not greater bump in torque. Also the car will spool significantly faster with cams as well. You have some sort of issue IMO, you checked the obvious things (cam timing, compression) so I'm at a loss

I am referring to pump gas tunes so that's a variable and your running a 20-9 right(?). What else is different?

 

Hes just not lifting to shift.

 

Yeah, I agree that something is wrong. 0 gain from cams in any part of the powerband and then a 200rpm loss in spool means something is wrong, but like you said, I tested the first two basics and found no issue.

No, I have the stock 05 turbo, but I think 20g-9 would help.

Chrono, you say you've seen those 20-25whp/wtq gains with cams (which I would expect), but have you seen those gains on a car already pushing max boost on alky or race gas with the airflow maximized? This may or may not be my problem, but I don't have enough data from other Evos to compare.

 

The cams should help even if you are maxing out the turbo. The cams help push or pull the peak TQ curve. In our cases they are used to push the TQ curve higher. Stock cams I assume are designed toward the 4.5k mark. Most aftermarket cams are designed to try to pull it much higher 6k-8k.

I would check your tune at these higher TQ marks... perhaps your tune was good for where the peak TQ was, now it needs to be tuned higher. Sometimes swapping cams alone wont make much or any power until you tune for them.

 

Oh and alchy is not the same as race gas You can get close to race gas level boost but you cant take the full advantages of straight race gas unless you are using it.

My timing had to be set pretty low for high boost on alchy. With race gas I can get away with more timing giving me a decent bump in power.

 

Trina, I was fully custom tuned after the cams, of course. I would never add cams and not get re-tuned, nor would I mention not gaining power if I added cams without a re-tune. After tuning, I have the 100% exact same power curve from beginning to end except for the 200rpm later spool.

Yes, yes, yes, I know that alky is not the same as race gas, but damn, you've been getting way too literal and technical on us lately. WE KNOW these details, but for all intents and purposes, IN MY CASE, running the alky daily on the stock turbo is EQUIVALENT to the race gas setup I used to use with my own crude SAFC tuning with narrowband o2s. I was never properly custom tuned...I was just tossing in race gas at the track and self-tuning with the SAFC. I consider my daily alky custom tune to be equivalent in power to whatever I managed to get when tossing in race gas with 93 at the track. There ya go...hope it's clear.

So, from these comments, you all agree that even with the altitude and having my boost cranked, I SHOULD definitely see a difference somewhere with the cams. I used the same dyno, and the conditions were within 10* and the same humidity with the same barometric pressure.

 

Not cars with the porting, in theory if your car flowed well enough you could be maxing out the turbo earlier but there is a problem with your symptoms...You lost spool and didn't gain torque, if it were an "too much flow" limiting your hp gains up top your car would be a beast down low right? It should have a killer low-to-mid-range but you didn't see gains anywhere which brings us back to somethings wrong.

I jokingly agree with an earlier poster who suggested you accidentally put the stock cams back in! Go check your "stock" cams and see if they say "HKS" on them

I really would like to see your car on the DD dyno, the curves look much more representative of what you'd see anywhere else. I had my car on both BTW and the DD ones peak where they should etc.

 

Short shifting is shifting earlier in the powerband. Different than speed shifting.

 

I will be exclusively on a DD as soon as Revolutions Tuning has theirs installed in a few weeks.

I know it seems like I still have the stock cams, but we pulled these right out of their plastic bags and put them in. I can't think of anything else at this point.
