The only change between the Red graph and Blue graph is Meth and 24PSI compared to 30PSI Both done on 93 pump

I've seen a lot of requests for before and after meth so enjoy

BTW: Aquamist HFS-5


Before meth:
24PSI

After 100% Meth:
30 PSI taper down 28psi

I think the gain is impressive again only difference is Meth and no Meth.
WHP peak: 27.46 gain
WTQ peak: 83.87 gain


I should be able to get higher numbers, my rings are gapped wrong (rimes with uven) and I burn oil, this will be fixed in April by the Master Sean at Iveytune. I also currently run 264/272

It appeared the cam is retricting some high RPM flow. Stopping the engine from breathing in more air. I am sure the new cam will take you over 400.

The mid range gain is impressive.

 

yes that is what Sean said...

 

Nice torque spike man, that is insane! +100wtq in one spot!

 

I think the BOV might be opening will finish it tommorow.
Engine has over 20% leakdown in some cylinders but we will still try with it.

correct me if im wrong, but those numbers seem beyond weak on a dynojet

 

Great results. Very similar to mine.
Here is my sheet with straight 272s - same snail, meth, same tuner of course...

 

 

Great gains, but I'm confused. You state the "only difference is Meth and no Meth", but it looks to me like the difference is Meth plus 6psi of boost.

A true apples to apples comparo would be at the same boost level me thinks.

 

Yes you are correct I'm guilty lol... Besides the boost being different yes everything is the same.

I understand... I meant if you run meth compared to not running meth. I was not doing an apple to apple match up. Guys always look for the benefits of running Meth so I posted what I found. Sorry to disappoint you.

I corrected what I said so it is clear.

 

Simple enough to explain - it's the meth that allows the extra boost without knock, hence the extra power.

 

Exactly. You need to crank up the boost, lean the AFR, and up the timing to take advantage of meth.

To the OP- looks awesome, that much torque must be fun as hell.

Kinda hard to tell on the scanned dyno , what RPM do you reach full boost?

 

those are some good tq gains the power isn't much though. The car is not making much power for a dynojet.

 

Great gains indeed. I love Meth - or rather - my car loves it!

 

EVO11V -

Do you know what A/F you are at and how much timing? With 30psi you should be over 400hp.

Here is a run on an EVO8 we did during development of our VCS3G controller. Everything was stock on the car except the MBC.
