[Quattro v1.0]

So little yet so powerful...

...THATS WHAT SHE SAID!

Hank,
What is this little turbo?

probably related to the head posted above...

[Hank]

It is a little IHI RBH31 with a 21mm inducer turbo. It is a designed for engines making anywhere from 25hp to 85hp!! Should have our little 250cc engine spooled up by 6500 and hold boost to redline at 12500

[quattro87]

I call misdirection.......Hank is finely coming around to the value of early spool in his Urq. I think he figures that he ought to get full boost at around 1.5k rpms on the stroker seeing that he will have more displacement at 2.6l. :wink: I've been telling him since high school that he doesn't need such big turbos. I've never been able to get through to him until now it looks like.

[nismo]

He'll need about 12 of those for the 2.6!

Just 5. One per cylinder.... ;-)

[fasterthenrs2]

Hank I do not like light few at all so hard to drive them on a street

[nismo]

5 of those mini turbos wouldn't do anything. 85hp x 5=450hp ...well shy of what he needs. 10? Yeah, that would be about right.

Hank, was your 512whp setup on E85 or pump?

Lookin' really good, Hank. Keep it up-

17 Days!!!! Get in the Lab!!!

I got to the shop tonight for a bit tonight to finish off the 996tt brake brackets and mock up the tall deck for my new header and downpipe. I am still waiting for some stuff to finish off the wastegate, but everything looks like it is going to fit with stock motormount position given that the motor is solid mounted. I wanted a new valve cover before bbq, but I only have two saturdays to finish up.

Looks great Hank! Keep it up!

[Hank]

I got down to the shop for a couple of hours tonight after school. I needed to make a crank pulley so I could get the assembly dropped off tomorrow for balance. This is what I ended up with. I wanted to start off with the AAN pulley as the rubber is usually nicer and lots wider than the 7a/vbelt stuff. I thought about going serp, but I want to go electric PS pump, so the only accessory I would have is the alternator. It just made more sense to go with a vbelt setup. I trimmed the AAN pully down from 11.5lbs of the old setup to 6lbs of the new one. Most of the weight is out side of the rubber so I am confident that hte dampening effect will still occur. I also deleted the chunks for the crank tool as I rarely use it anyway( I typically tighten in gear with the ebrake on). Got my new trigger wheel on, and hopefully this setup will yield easy starting with the good signal.

[Hank]

oh, and my favorite part. I machined the v-belt groves to accept the available gates belts vs the super skinny belts NLA that the car really wants. Hopefully these like 8500rpm a bit more than the last ones

[scubadave]

Nice work Hank. Does it matter that the keyway is messed up though?

[Hank]

Yes, it is holding mr up atm. I noticed it late last night. I will order one ASAP. Wherre did you order yours?

[ringbearer]

$70 @ GenuineAudiParts

Too bad Marc no longer has the forged version available, that was a nice piece

[loxxrider]

Yeah... I might have to talk to someone about making those again.

[Audilard]

No more phone calls asking for a ride to BBQ. This car better make it!!

[ringbearer]

Yeah... I might have to talk to someone about making those again.

If you can get them in a month I'm in. TB needs to be done soon.

[loxxrider]

I have a way to get them made, I just need to make sure I'm not stepping on any toes first... after I get that straightened out, I'll move along with it as quickly as possible.
