Anyone got the various dyno day results handy? I did a search but couldn't locate the results. The posts were all there but I suppose the pics/attachments are long gone since switching to the new Forum. I am looking specifically for dyno numbers of the ztube ONLY in the coupe with 5AT and dyno numbers of the ztube with K&N (again, in the coupe with 5AT)

Thanks in advance,
MA

 

Here is my car on a Dynapack. . . Stock w/ just a Z-tube, no K&N, 4th gear, ~5k miles IIRC.

 

so there's aa 2.4 HP gain? pls correct me if i'm wrong

 

Looks like 7-10 HP gain @ 5k RPM and @ redline. It looks like it basically smooth out the HP curve. Not bad @ all.

 

Eldy simply posted his dyno runs (w. Z-tube). It is unfortunately not of any use to determine Z-tube gains unless he's also got a baseline performed w.o. Z-tube.

Stop confusing these poor souls Eldy!

 

I guess I didn't clarify... All three of those pulls are with the z intake tube.. there was no baseline done (with the stock intake tube instead of the z's).. Honestly though, the z-tube is just a noisemaker. Kinda like a kazoo only more expensive.

 

here's what I have... There are 3 different cars, all 5AT's. One is completely stock, one has the z-tube and stock air box and the other has the z-tube and pop charger. All cars were dynoed on the same day and on the same dyno.

Also, G35Sean just did a dyno last Friday on his 5AT. He did 100% bone stock (well he had a K&N panel filter) and then re-dynoed and just added the z-tube.

He will re-dyno this Friday with the Crawford Total Package (and z-tube) to see what gains he's made. PM him for more info...

 

Yes I did a baseline dyno (well with K&N drop-in) and then added the z-tube. I gained 6hp (from 227hp-233hp) from the z-tube. I will be getting another dyno this Friday on the same dyno with Crawford plenum, headers and cats. I'll post all dyno data as soon as I have it.

 

can i ask why this is in the FI forum. i remember that chart neffster. what a day!
