After the mega high of yesterday's massive 375 whp Evo IX - today was a return to reality with a 2004 Evo 8 and a

K & N Typhoon Intake
3" exhuast
Forge UNOS
Walbro fuel pump

21 psi of boost

93 pump gas

It made decent power compared to the IX it was nothing

BUT - at least it aint a slowbaru !

 

still a decent amount of power

 

it made decent power without cams

 

True- also this is a 93 octane tune vs 100 octane on the 9

 

Are you purposely trying to make us original Evo owers feel bad?

 

 

what a d***!, lol, j/k al

 

AL! i am gtting a down ic pipe and a front mount intercooler from perrin.My question is would i need another reflash? and how much whp would i get?

 

Those are very good numbers considering its on pum gas and its an 04, which DOES NOT have the 10.5 hotside. With the hotside it could have easily made 330+whp!

 

Al, are you finally getting good #'s with the k&n Typhoon intake?

 

I feel just as bad - trust me - I am trying to sway my wife but she is ready to divorce me immediately if I get another evo

 

See I would beg to differ with Al on this one. This is a perfect example of a strong 8 that with cams, 10.5 hotside, and 100 octane/more boost would have came close to what Al made on that 9. Al do you agree?

 

I should have posted the before dyno sheet ! I will do that tomorrow or in a day or two when I get back to Pruven

The before sheet was pathetic

I have figured out some decent tuning for the Typhoon which works well.

Still - it is not one of my top intake choices

 

I would say that the 2005 evo 8 would be about 35 - 40 whp lower than a IX with similar mods and 100 octane

They are both great cars - just one has a more advanced turbo and can hold more power iwth high boost

NOTE - with pump gas boost levels 20 - 21 psi the difference is NOT AS HIGH between the two

The IX starts to have a bigger advantage with higher boost

I would suggest that a good POSSIBLE explanation may be REDUCED HEAT in the intake charge due to greater comprssor efficency in the higher pressure ratio areas

 

Is the cold weather helping these cars? Do you think the "Hot Summer Days" would hinder them at all, like it does the 8?
