    Speed Density Combos

    When a dog bone slipped out and my SD cam got eaten up, I went to that 15511 cam. It ran fine but at idle it would run rich. Never could get it too not idle rich, so I converted to MAF with a 70mm SN MAF unit.

    Help putting a combo around TFS 170 heads.

    MAYBE, but the cam choice is critical. Not real likely with a street friendly idle cam. When you increase cubes with a GT40 intake you need more cam to make power. On a 347 they peak out at 5200- 5500. Run more cam and it might happen at the expense of street drivability. Check with a good...

    Engine GT5.0 Intake vs. Edelbrock Performer RPM

    The Power glide 2 speed transmission. He made more peak power with the Box-R but lost average power. He needed his torque curve to be FAT in the one shift range for shift recovery and hang in therethrough his stated shift point. The torque (average hp) lost was too great with the Box-R to...

    Yes, but there is a bigger factor as the reason for that need.

    Engine GT5.0 Intake vs. Edelbrock Performer RPM

    Air speed yes but why was that important? Race car with Dart 331, custom blower cam, YSI, AFR 205 heads, Powerglide with high stall and gears.

    Engine GT5.0 Intake vs. Edelbrock Performer RPM

    which intake is better depends on the whole car build. I ported an rpm1 intake for a blown 331 race car and it flow tested 277 cfm average (we have ported then to flow 313 cfm) when I was done. It went on AFR 205 308 cfm heads. He tried a Box-R intake to go faster but couldn't and when he...

    Engine GT5.0 Intake vs. Edelbrock Performer RPM

    The stock Explorer flows ~205cfm average and your heads flow mid-190cfm so no real need - BUT You could port just the two front runners short side radius per my instruction article to even out flow distribution. Since the heads are the restriction it might not result in a noticeable gain.

    Engine GT5.0 Intake vs. Edelbrock Performer RPM

    the s The stock upper has a 63-64mm TB opening, so you can run a 65mm TB on it and have a .5-1mm ring around the edge - not enough to affect flow or power and is a no-work work mod. My page also has an article on porting the upper as well. Porting the upper will help lift the rpm band some...

    What intake is best for me?

    Just for the record, we flow tested a stock Saleen at 220 cfm and the Holley at 258 cfm. If you looked at both lowers, you'd know why.......

    Engine GT5.0 Intake vs. Edelbrock Performer RPM

    Well, you bought an Explorer and that will work well in stock condition. If you ported your stock HO lower, left the upper stock and ran a 65mm TB on it it would flow almost exactly what the GT40 heads flow. I'm sure you could find someone in Germany to port your lower - only question is cost...

    Bad MAF symptoms

    Looks like your regulator has a recessed allen in the center of an external jam nut. DId you loosen the jam nut before trying to adjust the pressure with the allen?

    Help putting a combo around TFS 170 heads.

    Since you have an automatic, don't get too targeted on making a certain rwhp goal, the torque converter determines a lot. You can dyno a certain rwhp then run faster than you should on the track. 330-360 rwtq is attainable if you get things right and that will run into the 11s with traction...
