any one do a dyno

 

no gains other then a 10 to 15 * drop in iat2 temps

 

dude more cfm = more power, lower temps = more power

 

nothing noticeable maybe 2hp

 

no one has taken a dyno afterward

 

I've heard 5-10 but I have no clue and have not seen dyno proof...

 

Its more like asupport mod.
it lowers your iat2 temps, and takes away another restriction, kinda like what a header does, only going into the engine not coming out of it.

 

Redlines suck. My blower was ported and my IAT2's are decent, but I have a Cobra HE, too.

 

I will be able to gauge some kind of realistic numbers in about a month or two. I have a spare M62 supercharger at my house I am sending out for a real port and polish. Going to keep the same 2.7 pulley from my other supercharger and run before swap and after it before tuning on the dyno. After the first two runs I will dyno tune for the third and forth run to give an idea on power numbers and IAT2 temps.

Hope this helps.

mostly a support mod... maybe 10hp at the most... mostly used for cooling your iat's ... bascially like everyone else is sayin

 

I have a dyno setup all ready to go. I got one baseline, I'll be getting another one once my header is done (i have the intake and exhaust on also), 1 after stge 2, and then I want a ported blower to take on there. My only problem is getting my hands on another Supercharger to have ported as I don't wanna port my stock one. As soon as I can get one, I'll have a Dyno # up here.

 

why does my friend say that a stock ss/sc has only 180 hp to the wheels but he said it really has 205 i dont get it if u run a stock ss/scon a dyno wont it read over 200

 

cause he is a nutcase... simply put..

 

Didnt Answer My Question But Thanks

 

it really depends on what dyno. where i was dyno'd stock ss s/c #'s were about 190whp/185wtq

 

Funny, i thought there was another Shab at the redline forums....oh well.
A cobra heat exchanger to my knowledge isnt to lower your iats, but to fight heat soak by having a seperated core that is self cooled by air, then re-circulatd thru the rest of your intercooler system.

My approximate iat2 temps were 140 to 155 at the very highest.
once the porting was done, i dropped roughly 10 - 18 degrees.
I also added the dual pass endplate to my intercooler system as well.
Now my iat2 temps never get any higher than 125...ever.

Another reason to port the blower, less pressure bieng built up in the cylinders.
you do lose boost according to your boost gauges, but your still moving the same amount of air, your just doing it with less restriction, making it a tad easier on your engine.
I was at 17.5 psi, im now at 13.85 according to hptuners. Am i any slower?
Someone said they actually raised boost thru porting thier blower...i cant see how they managed that, but it may only mean that there double stacking. thats building pressure upon pressure upon pressure. Acts like a clogged up cat. Whoever that is, i sure hope it isnt true.

Anyways my conclusion porting the blower (THE RIGHT WAY!!!) ftw!!!




Oh shameless plug, for all your ported blower needs, contact Euthanasia, awesome work, price, guy, everything. You will not be dissappointed!

 

He is quoting magazine numbers.
a stock ss/sc has 205HP at the crank as far as official factory numbers.

Normally, to get the Wheel horsepower (WHP) you have to calculate in drivetrain loss
which would probably bring it down to about the number he is saying.

Crank HP, is the horsepower created by the engine,
wheel horsepower, is the horsepower measured by a dyno, that includes losses due to drivetrain.

in the real world....the ss/sc was very underrated from the factory, mainly for insurance purposes...

In reality, the ss/sc dynos between 205-225 at the wheels.
which would suggest a crank horsepower around the 240 mark.


Hope that helps.

 

hey, are there any how-to's on how to port the blower?

 

I know if you port the blower, it makes it alot louder than stock... or at least I know it does on the 03-04 cobra's

 

You thought there were two different people with this handle? I'm confused. I somehow disappointed you?

A Cobra HE is a good idea to prevent heat soak. But, having heat soak does raise your IAT's. Steigemeier ported my blower before I had an interceptor to monitor those numbers with, and I didn't manage to go to a dyno before or after the work, so I can't give a very good comparison, I can only say that my IAT2's rarely go over 125-130 on hot days when I am beating the crap out of the car, and if they do, it is literally for only seconds.
