I dynoed the cabby on sunday and here are the results
with a dr. diesel high lift cam and a giles pump and k26@24psi egts 1600-1800
EGT's were WHAT?
How much for the cam??? You sir are killing me, I need to put A/C in my build car...heck I just need to get it done.
this is a mech cam we are talking about here to be certain, correct? if so I highly awiat the numbers so that I can use this in my build looks great, keep on truckin.
Thanks,
Kevin
Actually, it's a hydraulic cam. It's likely that it could be used on a solid lifter engine, using lash caps between the valve and the lifter. Perhaps we'll get around to figuring that out in the future, but for now we're deeming them for use in hydraulic engines exclusively.
We're rapidly closing in on the official release date for these cams. We'll disclose all the info and specs on them then. We believe you'll find the pricing quite agreeable.
I'll tell you this now:
On Giles' B3 modded AAZ Passat, installation of this cam with no other changes resulted in almost an entire second shaved from the quarter mile time.
Giuliano's results below speak for themselves.
Even on my stock-everything AAZ Passat, it made an improvement in the mid to upper-mid range, but was clearly truncated by the govenor.
More soon.
To speed the process, see Burn_Your_Money's post requesting AAZ valve face depth measurements.
COOLNESS! I readily await the results, especially on the mech cam details.
take care, and God Bless,
Kevin
great numbers!! 8)wow those EGT's were NASTY high
.....I would be scared to take mine up that high....how long did you run at that temp?
well... the good news is that now you have a forged/cast aluminum head
I don't know, certainly possible, as the exhaust gasses are passing relatively quickly and exiting the exhaust at a very high rate of speed and low back pressures, due to the way the engine is setup.
There's also the nagging question in the back of my mind, "just how accurate is this gauge?" I've done some pretty mean things to diesel engines, and haven't EVER suffered a failure that could be attributed to over-temping the exhaust.
with those kinda EGT's I would be thinking REAL hard about spraying water!
I think they would come down substantially if the exhaust leak pre turbo was fixed.
This isn't a stock cam btw, it's a custom grind.

Now I wonder, with those kind of egt's would meth injection be too cold and cause cracking, or worse, KABOOM!
kinda like dry ice on a hot water filled glass. How cold is too cold with something like this? cryo cool "spray liquid co2" the intercooler and use meth injection maybe? Sorry to be off topic.
On this cam is there no time when the intake and exhaust are open at the same time? I figure that would be best for a turbo app. Also, I knew it was a custom grind and I am going to be in need of a Mech one though...but like I said I just need to get it done.

I would only spray water...no meth...plus if you set your system up to start spraying before the high temps then you got nothing to worry about....spraying water is a good thing IMHO
I know my set-up will need water Injection...soon if I wanna run it at the track at full pulling power.

Nope, there's no room to have any overlap - the piston is essentially flat against the head at TDC, so you can't possibly have the intake and exhaust valves open at the same time like you would on a gasser.
Actually, there's a suprising amount of room for overlap.
Not that we're gunning for a lot of overlap, but if a little extra comes from a LOT more lift and duration, small price to pay!
Very nice work. My egt's are never ever that high. I'm now my self extremely curious what my car will dyno when i have a clutch that will handle my foot on the floor.
I did my own pump mods - for the most part it's still stock. I have a 1.6 bottom end and a smaller downpipe (yours is HUUUGEEE).
that thing is laying down some mean torque numbers and i LOVE a table top dyno sheet (the read out looks like a table). None of this ... gasser staircase dyno crap. Why would you ever want to make peak power at the tail end of your RPM range? peak torque at 2,750 sounds good to me =)
HP numbers may be low but HP means nothing... i'd much rather have big torque and low RPM (HP is just torque * rpm [with a constant number in the middle i dont remember what it is])
I can't wait to dyno mine now. I'm hoping for 90hp at an unknown amount of torque.
My ONLY ... bother with your build is that you put that stinking bus bar on the glowplugs when you had them out! dude you
gotta pimp your glow plugs
