If I can pick up 35-45 whp from from my new mods I'd be happy...to be honest these mods don't really start kicking in especially the inlet pipes till the end of 3 gear...I feel my car runs out of steam like its got a anchor attached in 5th...hope these mods can help with that...

PTF was running big cfm through a 3076 making 900AWHP so a bigger inlet would free up some big HP.


Just for a more exotic vehicle feel with quick throttle response and freer revving motor , the GT3 THROTTLE BODY and the IPD plenum is worth every penny! If you do go bigger turbo later those two mods will keep helping you the more you flow.
+1. Bigger turbos equal more air...just didnt agree with other members comment about not much at all...btw...you didn't give your guess on number...

Those are great numbers for 93 pump and the previous mods you mentioned. My guesstimates were based on numbers like "Kricci" on a mustang and pump with similar mods to yours and "A428t81" on dynojet on E85.

But the numbers you posted are giving me hope since I am in the process of changing things up with mine. I am installing ID1300s, do88 inlets, Kline catless, intercoolers, colder range plugs and tuning done by PTF using COBB on E85. I already have a GT3 TB, Sharkwerks carbon Y-Pipe and Plenum. I was shooting for 560-570 whp on a mustang on E85.

Thanks man! Appreciate the comments, i love it I had a custom tune done at Cobb's facility.

You put down some great numbers - congrats. I went to Cobb's facility in Plano for my tune. I'm curious why such a large number swing - i realize all dynos are different and there are a lot of factors that can impact the tune and the numbers, but seems my numbers are ultra conservative compared to what others have achieved with similar mods.

How about if I told you that I know a supra that dynod at 600 whp on both a dyno jet and mustang on the same day.....I've been around cars for 20 years and dynos are bull rap ...they just give you a baseline of what your car is around....please also believe that dynojet and mustang dynos only have like a 6% diffrence so it's not that huge...maybe 20 to 25hp...max..

It all depends on how the Mustang dyno is calibrated. I have seen 70whp difference between a mustang / dynojet ran the same day, same car, 700whp range.

But I fully agree that they should mainly be used for tuning tools.

This probably isn't news to many people but to those who aren't aware.. Every dyno reads differently and can be manipulated differently. Honestly, once you run a dyno and see all the things you can mess with you'll never take an internet dyno post seriously again.

Use it for back-to-back parts & tuning comparisons only. Then go get a trap speed.

True, I installed the Mustang Dyno software on my laptop and got the TIB files from my dyno runs and was able to import the data into the software.. Lots of things to play with and you def can see how a dyno operator can affect the numbers.. Just the WCF alone can sway it by 10% in either direction if they override the values. And then there's the curve filtering, etc. etc.

I was mostly interested to see the delta in my uncorrected numbers between mods..

And of course I have the 60-100 and 100-200 vbox times that allow you to eliminate some of the dyno variables.

And lets not forget that dyno tuning best way to really dial the car in is actually driving it on the road...can't get better then real life pulls and logging and tuning ...a little dangerous but proper..
