those are some pretty impresive numbers. looks like my hotside and cams will be coming sooner than later.

 

Back a year ago MR's with similar mods were making on the average 330 - 335 whp

It stands to reason that when you spend literally every day tuning Evos of various states of modification - over and over and over - that in time you will learn new ways of looking at things and unlock new ways of finding additional power.

I think that no matter what you do, if you dont constantly strive to get better at it and improve then you're prob on the way out. The best part about this for me is that I love working on Evos and my work is what I enjoy the best.

 

I think its time for some new cam shaft testing actually and when I have a chance I am going to do a new study which includes the staggered cam combos

up till now I have always recomended 264/264 becuase when I originally swapped from 264 / 264 to 272 / 272 on my own evo back in May of 2003 I only picked up about 3 or 4 whp and lost about the same in tq. Basically the power curve just moved up slightly towards the higher rpms.

When running the stock turbo and stock engine it seems that the rpm range is BELOW that of where you will see the 272 advantage really start making more power.

The 272 starts to have a rougher idle than the 264 which idle nearly like stock.

The MR in this test with the 272 intake and 280 exhaust had a really nice idle. It was really different it was racy and lumpy yet smooth and totally stable.

This particular car came out really good on the driveability, it was really smooth and a great power band. It was one of the best I have tuned to date. Whether this is due to the cam stagger or just the individual car I am not sure.

Basically, what I plan to do is try and test all the cam combos out on the same car on the same dyno and the same day.

Obviously that test is going to be a marathon of work and effort but I think it will be worth it. I have some new Forced Performance cams I have been waiting to test and this will be a great excuse to do it.

 

awsome! cant wait to see what the tests show..

 

arrrrgh!, you're doing it again..... first you claim an extra 20hp from a year long odyssey of "passion" tuning, and now you say it's possibly just an anomaly?

Friendly suggestion.... stick to tuning and hire someone to do your copy, no?

I don't question the dyno numbers, I'm sure they are ligit, but you need to work on your presentation of the data/information

 

It didn't look like he said it was just an anomaly...he was referring to not being sure if the exact attributes this car displayed were because of the 272/280 stagger or just the car itself. It's not so much the power it's making, but how smooth it is as opposed to other cars with 272s and 280s. The part you quoted was when he was referring to the idle qualities of 264s vs the others, not so much the difference in power...

 

I am assuming that he was using stock cam gears..

 

Now would an 03 with the same mods and the 10.5 hotside be able to make similar power? If not what in particular is holding the 03s, and 04s back?

 

I'm a potential customer, as I am looking for an ECU flash. I read the thread as a testimony to Al's tuning skills to make more power. He does seem kinda big on himself in this regard. You read the thread as how smooth the power is delivered.

You say tomato, I say tomato..... jeeez, that example doesn't work to well over typed formats

regardless, if I'm confused about what he meant, well that's not saying much.

 

I think this is the same guy who came to the shop last week and bought these cams from me. If its the same guy, we went back and forth between 272's and 280's and finally i suggested he try this setup because it should offer the best of both worlds. if its teh same guy, good luck with it man!!!

 

yeah i would also like to know this. I have an 03 and these impressive 05 numbers make me feel like crap.

 

Very good advice you gave him !

I want to see this combo again - it was very good.

 

You can't identify a trend from one car or two cars

Like when you look for a global warming TREND you average the individual samples

Just last week I shattered all previous stock turbo pump gas reflash records with case study #104

https://www.evolutionm.net/forums/sh...=166264&page=1



So here we have two cars in the 359 - 369 , 93 octane pump gas range

There were a few others I did recently also which were in the same range

AND - the kicker - the car in case study # 107 - the car in this thread put down 373 whp on its first pull today when the boost was accidentally set too high - 25 psi

The car had some knock with the pump gas at that level so I did not post up that sheet

The conclusion I reach is that I am onto a few things on my tuning and I have reached a new threshold of power

Keep in mind these cars had stock TB, stock fmic, stock injectors, etc

 

Thanks for clarifying that

The anomaly was that this car felt really tight and well sorted - not ricey if anyone knows what I mean by that

 

my goal here by continuing to post so many dyno sheets on the foums of my work is to help to educate the prosective customer how I tune and to show how various modification combinations work together


I am BIG and I am BIG on what I do !
