I had my 97 cobra dynod yesterday and it was quit disappointing 191rwhp 255rwtq now i dont need no one saying how bad that is, its quite obvious im told its my imrs not even opening should i attempt to clean them or just remove them.

[zigbigadoru]

remove them

[red96stang]

how bad is the low end torque loss..

[zigbigadoru]

i do not know specifically because i do not own a 96-98 cobra but what you lose in low end torque you should gain in high end horsepower

[red96stang]

i hope not quite that much thats like 60tq cuz thats about how much hp im loosing..

[zigbigadoru]

ummm it shouldnt be THAT much torque but maybe like 15-30 ft/lbs? this is only a guess as i havent done this. like i said im just taking a shot in the dark here

[red96stang]

i have also heard that it falls on its face what does any1 think of that i havnt tore in yet not sure what im going to find if its just gummed up i can clean it i dont know what to do if its broke...

Tuned you wont loose hardlly anything. I know you need to add around 5-6* of timing under 3500rpm when you delete them on the 3.8l.

[red96stang]

well i am going to put a blower in a few months hopefully so im not going to tune it right away but its a dd and as long as when i decide to race some1 or im driving around cruising its not going to fall on its face under 3250...

[98Cobra_sleeper]

if you are going to put a blower on then remove them. they are a restriction when you boost. take them suckers out. modularmustangracing.com sells delete kits.

[red96stang]

how will it drive under 3k with no tune until a blower

[98Cobra_sleeper]

i'm not sure without a tune. call a tune shop and ask

[bitemark46]

Just add timing in the low end as someone above mentioned. When I did my shortrunner and IMRC delete I lost ZERO torque because I added timing. No IMRC's and a shortrunner I have almost 300rwtq.

When the blower goes on you won't even feel it.

It sounds like they are just so gummed up they dont function.

Personally I would just clean them.
The reason they get so gummed up is because of the egr.
Delete the egr and you wont have problems.

I'd definitely delete them when you add boost.

For right now you can try seafoaming a couple times, and see if that doesn't get 'em freed up (just do the vacuum system, don't waste it in the fuel or crankcase).

[red96stang]

i can manually move them by reaching in there but the motor isnt strong enough to do it but im gunna temporarily tie them open ill let you know how it drives and if it works

[98Cobra_sleeper]

totally forgot about the seafoam. that stuff works great.

[red96stang]

hahaha i zip tied the butterflies until tues. when i delete them and the torque loss isnt as bad as every1 says there is a slight loss. but i am seriously surprised at the hp gain will let you know the new dyno numbers soon....

anybody ever seafoam there car?

i've done it.

b heads would especially benefit form a seafoam.

Dont bother pouring it into your gas tank or crankcase (thats just pure stupidity to me)

Just let it idle and pour the entire contents of the seafoam into a vacuum hose. Don't let it die...

Once there is none left, shut of the car for 5 min.

Then start it up and watch what comes out of the exhaust!
