The old rule we sometimes hear that "the whole is equal to the sum of the individual parts" does NOT hold for mods. With modding the whole usually does not equal the sum of the individual mods. It all depends on how well the design of each manufacturer's part plays in combo with another manufacturer's part design. I have had times when one CAI and exhaust combo made 27 HP and then I switched out just the axle-back and actually lost 8 HP but gained about 6 ft-lbs in TQ. Some mod combos work well with each other and some don't so that is why one cannot rely on any "sum of the parts" rule.

For me I just wait and read the results of other people who spend their cash looking for "power" nirvanna. Once I read about a certain combo that shows great gains for someone that is the one I usually go for. But I also understand that putting this particular combo on my car isn't a guarantee that on my car it will show the same results as the person I read about. It just means that the odds are in my favor that the results will be spot-on or near spot-on.

There is always a "crap-shoot" factor I stay aware of when doing a particular combination of mods so I don't get too disappointed if the results are less than proven by someone else.

307 - 273 = 34

I wasn't referring to the Headers and pulley that he added, that's why I only mentioned intake, exhaust, and HFC. Also I was using a rough estimate based off what others have gained from these three mods.

Oh, Gotcha ya. Ricer math would say about 30 to 35 on those parts so a real world 25 seems about right to me.

DynoDynamics results are in.....
 

Well...got her dyno'ed again today. This time on a DynoDynamics machine. I expected it to be low so I was prepared for it. They dyno'ed it in 4th gear where I believe Altered used 5th gear. I asked about that and I was told the results would have probably been about +5 whp if it had been done in 5th gear.

Anywho.....heres the results along with my last DynoJet result:

DynoDynamics performed 22 August:

My last DynoJet result performed 7 August:

"I was told the results would have probably been about +5 whp if it had been done in 5th gear. "

Then why didn't they do it in 5th? :icon08:

They thought the 370 auto only had 5 gears! I told 'em...nope, its a 7 speed auto....I think his face was like > :eek:

You paid for service like that?

Yeah....I know. I'll just live with my DynoJet results. ;)

According to the shop I have done my dynos at, it does not matter on a dyno dynamics between 4th & 5th for a 6 speed manual he said. Now with the 7 speed auto I am not sure 100% really.

My understanding is that the 7 speed auto has to be dynod in 4th gear because the car will hit the speed limiter in 5th gear.

Hmmm.....makes me wonder if maybe Altered did test mine in 4th gear, then. I need to check on this and see.....hopefully they both used the same gear.

Mine read a little bit higher in 5th vs 4th.

Tony, sucks that the numbers weren't that great -- but at least it gives me something to compare to. I need to head out to Altered, though, and see what the difference between our cars is on a DynoJet.

For those of you that don't know, Tony and I went to the dyno today and I put down 265.4whp with my only mod being an Injen CAI.

BTW -- I have some video that I will put together and upload of your pulls.

Good to know m4a1mustang, next dyno run I go to (after exhaust is in) I will do first two in 4th and then a final run in 5th.

You should consider telling them to do it again. Maybe they should consider asking how many gears a car has before dynoing it. Retards. :rolleyes:

I wouldn't sweat it, other than Mustangs being almost as close. As far as actual numbers between dyno's, thats irrelevant. They are tuning tools, nothing more. Great at telling you gains, but you can't compare them to each other as they are all inherently different.

Thanks, Mike! I just figured I'd go for it and see what I get.....just for the heck of it! :tup: And yeah....when I push that gas pedal down....I still feel that rush of power! :yum:
