SCT Tunes for the Shelby

[AFBLUE]

Hmmm. Don't know if I agree with their assessment based on other things I've read over the years. When at full throttle, the factory tube will collapse inward and reduce airflow (saw it in a video). The rigid tubes don't do that. More airflow = more hp (when also tuned to increase fuel flow).

 

Also less bends tends to equal less air turbulence. Ok I have just exceeded my technical expertise, but surfice it to say, I disagree with Brenspeed on this.

We aren't talking a lot of difference maybe 4-8hp.

You make a good point!That's just what Brenspeed told me!

Here's the link to Steeda. http://www.steeda.com/products/s197_inlet_tube.php

 

They claim 8hp and 8lbs of torque. This is probably rather optimistic. I can't remember where, but I thought I read somewhere where a s197 owner did a before and after dyno with the elbow and netted 4hp.

I'll have to agree that 4-8 hp + tq is a good deal at the rear wheels for $109.00

Researching the steeda elbow and came across this post

This guy claims it knocked at least .1 seconds off his 1/4 mile times

This SGT owner said Steeda told him he would need a tune if he installed the elbow. If brenspeed doesnt' think it makes any difference then they probably don't have a tune that would maximize performance with the elbow attached. Maybe there is no need for a different tune but I would want to be sure. http://forums.bradbarnett.net/showpost.php...2&postcount=108

 

I dunno guys. I'm gonna bow out if brenspeed doesn't see much benefit to the elbow. Not trying to poo-poo on this endeavor, but my plan has been and will be to get a SCT XCAL II and elbow, and take it to a local reputable dyno tuner, and have my car optimally tuned. That way there is no question that I've got the best tune for my setup/car. A little more expensive, but worth my peace of mind.

I would have to agree with you on that.

Increase flow would be picked up by the mass air meter , and the correct fuel would be added by the computer . So no tune is needed , all it cares about is keeping the A/F where the tune has it mapped .This would be simular to one day its 85* outside and then a cold front comes through and lowers the temp to 40* outside , the colder air is more dense but the computer adjust for it , thats why it feels so much peppier on the cooler days.
