Thanks Big Al, and the Pruven team for all the help......the car feels awesome!

 

Looks like its going great until that slight dip from 5400-5600 RPMS...any reasoning?

 

I run a tad less timing in that area to prevent against any knock - its peak cyl pressure zone

That area is so slight you can not even feel the dip what so ever

 

Is that a trouble zone for EVOs? I thought the higher RPMs would be more knock prone. It does look like the power continues to rise in the upper RPMs after the slight dip

 

Hey Al, How can I get the torque up on my MR?

I'm at 321 whp / 299 torque.

My mods are:

HKS TB exhaust
Greddy EBC (23 lbs. boost)
S-AFC ll
Walbro 255
HKS Twin Power DL-ll
HKS drop in sponge filter
Pump gas (93 oct.)

 

Just a reflash will gain you 25 of tq. SAFC advances your ign timing too much and the ecu winds up pulling too much timing.

The flash can seperately adjust fuel and ign and therefore can make more tq.

 

Definatly,

When i got my car flashed I picked up some amazing torque. Definatly recomend the flash, AL does some amazing things. Look at my numbers under my avaitor.

 

i see that these new MRs are making quite a bit of power compared to the other evo's. i have an 04 and it seems that it takes quite a bit of mods just to reach what was achieved with the MR. my question is this-are they making more power due to JUST the 10.5 hotside OR do they have a different cam profile?? has anyone looked into this or even spec'ed one out??

 

Every car is different however on this particular car the area of knock was near the point of peak cyl pressure or 5300 rpms

After that area the car was clean to red line

Other ars may have knock problems at higher rpms - paricularly if they do not have good freeflowing exhausts

 

I have not had a chance to examine the cams yet - however to me it looks like most of the power gains come from the new design turbo set up which is killer whne you start to riase the boost near 20 psi

Note* - We have seen similar gains looking at 03 evos and 05 evos which both have HKS 264 cams - the same power gains on the 05's - so it seems the turbo is the likely source of the additional power

 

Cams are the same, verified through CAPS.

 

whats new with the MR turbo?

 

Revised 10.5cm^2 turbine housing (from the previous 10.5 version) and a revised compressor housing. That's it.

 

oh ic, I was actually woundering how worth it would be to take the stock turbo and get it cliped, and polished ect.
