Mods Face Off Result: Frank Racing vs Dynamic Racing P&P Heads

This test consisted of testing the Frank Racing and Dynamic Racing P&P heads at the Mods Face Off 5 (MFO5).

Mods Tested: Frank Racing vs Dynamic Racing P&P heads
Date: 10/9/06 - 10/13/06
Dyno Location: SVS R&D, Sacramento CA

***Remember to always review and keep in mind the Mods Face Off Testing Methodology Q&A while reviewing these results.***

The Pre Notes:
There are a handful of things to understand before these results can properly be interpreted.

• The table below shows one 2005 Magnum RT and one 2005 300C.
• This comparison is not truly a fair comparison
  • The "Before" numbers were taken from the GIFO4 numbers for Meister's 300C. This is normally a very bad idea as so many things could have changed between the tests. However, its the best we could do as finances, timing and logistics just didn't allow a before install test on Meister's.
  • At the time Meister had his heads and cam installed, he also had his headers ported. This alone introduces an unaccounted for variable that by all rights should bring the before to after comparison into question.
• Both MattRobertson and Meister installed the MDS Friendly Comp Stage 1 Cam.
• The results below are NOT head specific. Keep in mind, both cars received identical cams in addition to the heads. True performance increases due to the heads alone are not known or demonstrated via these numbers.
• MattRobertson's Magnum only had two comparable pulls in the after phase of testing (the third pull's data is unusable).

The Post Notes:

• Given all the variables introduced here for Meister's before and after results, how can we hope to learn anything useful from these numbers? To be honest, I'm not sure we should draw any conclusions. This should rather be used for reference when considering your options in head manufacturers.
• Frank Racing made it very clear very early on that the heads provided for this test were going to be "mild". The numbers indicate this is the case and in fact Frank Racing has taken our results and used them as a baseline for further improvements.
• Flow numbers are pending for both heads
• Frank Racing has
  • built these heads from stock 5.7L heads.
  • built these heads to support a camshaft with a maximum lift of .600.
  • included Comp Beehive springs and all required associated hardware.
  • The heads we received utilized stock 5.7 valves. However, Frank Racing has worked with Ferrea and expects to be shipping these heads with Ferrea valves.
• Dynamic Racing has
  
  • built these heads from stock 5.7L heads.
  • built these heads to support a camshaft with a maximum lift of ???.
  • included Comp 918 valve springs and all required associated hardware.
  • Dynamic Racing heads ship with ??? valves.

Note the long tubes on Meister's car. Truly unfortunate we couldn't get a proper 'before' number on this car, plus an 'after' that was after the head install.

On a steeply-graded, smooth straightaway Meister can pull me by about 3-5 mph when we are both already "at speed" and at WOT. And of course he kills me in the 1/4 mile. That car clearly is put together right.

matt, you have more power but you're slower??? meister's car must be a lot lighter than yours.

[MomsR/T]

hmmmmmmm..............thats interesting. Your numbers seem to support otherwise. DOesn't seem to make any sense to me.

[MadCharger]

matt, you have more power but you're slower??? meister's car must be a lot lighter than yours.

Yet more proof that everyone puts too much emphasis on peak hp numbers. Look at the curve of both cars. Meister's car clearly has the advantage along most of the powerband, but for that one small spot where Matt's car peaks higher.....

Maybe thats part of it. Meister's car has amazed us since one our first track nights, when he was chirping tires coming out of first and second and running 3 or 4 10'ths faster than anyone at the track... and this was before SC came out (and he doesn't use the thing, anyway). There is just something about that car. He's got a hot build is the best we have ever been able to figure.

He's also got drag radials. Thats two tenth's right there. And long tubes. But these don't explain all of his gains. Going up a steep hill on a smooth highway road "at speed" (ahem) with us both squared off and at WOT, where I got the jump on him in terms of us both punching it and going for it... he reeled me back in and passed me at a roughly 5mph better speed while we were both under full acceleration. And on the road he didn't have the drag radials.

Did anyone search his car for that stealth nitrous system?

Sooo very true MC.

You gave me an idea... check out the two new added graphs in the first post. Pretty interesting...

[MattRobertson]

Yo CV... are you sure you have that thing labelled right? Look at the giant dip during the shifts (no, not the giant dip in the mirror... focus on at the graphs!).

That looks like Meister's car with his non-SC'd tranny.

Load the page and do a refresh Matt. I did have it wrong originally; you must have caught it right before I changed them.

CV - also looks like you were using the raised shift points on your run, and still built power back up fast enough to get even with them again...... Seems proof there that the raised shift puts you in a better spot after shifting, even if you had to go well beyond the peak power range.....

EDIT - Actually, I take that back. That cam of yours doesn't seem to have been past it's power range at all when you shifted - compared to the others.

[MattRobertson]

wow those curves are killer CV. And the graphs are deceptive... According to them I should be pushing Meister aside as the speed gets really high. Looks like the disparity really starts at about 90. But... uh ... golly if we ever were to reach or exceed such a speed on a race track somewhere I'll theorize that Jim would whoop me.

EDIT: Raised shift points were something I wanted to try at the track and flat out forgot to do... Bah!

[lafrad]

I'm still kinda dissappointed that you all didn't run the same shift points.. that messes up a lot, because they shift into different parts of the powerband...

[MadCharger]

EDIT: Raised shift points were something I wanted to try at the track and flat out forgot to do... Bah!

I'm not sure what kind of difference it makes in the 1/4 mile, but it's huge in the 1/8th mile - being able to carry across the line in 2nd gear, vs. shifting before. It made at least a .1 to .15 difference in my times in the 1/8th.

Proof positive we aint perfect; we all thought my rig was in 91 tuned with raised shifts. But, when we plugged in later in the evening, the Superchips reported we were completely stock. Yep, the runs you're looking for me are, according to the Superchips, stock.

Totally guessing here: could the difference be in pulling fuse 17? I had it pulled, Matt and Meister did not. Maybe it has to do with no MDS? The PCM was definitely throwing MDS related codes... maybe the Superchips was wrong somehow and in fact we were tuned after all??
