Craiger - What numbers did you pull down?

Craig 930 RS 11-13-2006 06:09 PM

438 rwhp and 413 rwtq - I think there is more in it & I may have a boost leak. I was finishing the car right before the dyno run I hosted..........and Murphy's law was in effect and I f'd up the IC install, leaving out an IC spacer. The IC is cockeyed just a bit.

Still, pretty good numbers -

VERY nice! Congrats :D :cool:

Pushing against the limits of CIS? Impressive numbers there.

Craig 930 RS 11-14-2006 06:18 AM

Good thing is wih the IA fuel head/Leask adjustable WUR & RPM switch & solenoid combination ---- nowhere close to the limits of CIS as far as fuel delivery is concerned.

Not bad ;)

Facey 11-14-2006 02:08 PM

that is an impresive pull.... and the turbo sound is growing on me...but it is an aquired taste....

really neat how linear your pull sounds (reving fast from start to finish).... in mine last weekend it started kinda slow then really picked up...

what rpm did u start at? 3k?

really nice car

Craig 930 RS 11-14-2006 04:30 PM

Started at 2,000. Alex (shop owner) said the higher HP cars rev pretty quick....makes sense, eh?

slow&rusty 11-14-2006 05:56 PM

Awesome and congrats!

David 11-15-2006 06:39 AM

Very cool!

Is that a fan on top of the intercooler?

I'm planning to remove my fiberglass rear bumper for the EFI dyno tuning. Did you notice the turbo getting hotter on the dyno?

Craig 930 RS 11-15-2006 07:13 AM

Alex bungeed a BIG fan on the intercooler.
The highest temps I saw on the 50 degree day was 80 degrees at the intercooler outlet.
I had him add a fan to the lower left to cool the K27 Hyflow turbo that Kevin made -
The turbo and especially the manifold join pipes glow a bit red during the runs ;)

SCHNELE 11-15-2006 09:35 AM

Ok, I am not that impressed:rolleyes: and why haven't you gone to a full bay intercooler? My well developed 930 made 379hp/365lb/ft with CIS so I would say that your car is pretty stout. I had stock heads, SC330 cams B & B headers and exhaust, Andial intercooler, K27/29 turbo (wherein lies the major difference, along with the heads)and euro fuel head, now that my EFI conversion is complete I should be in your ballpark ;)

Craig 930 RS 11-15-2006 10:43 AM

Looky what is waiting to be installed - after the monsoons have passed, that is.
The RUF IC outlet temps are now about 150, used to be 130 max on the track.

Is your car up and running? Pics/dyno runs?

Tom F2 11-15-2006 11:48 AM

Would you, please, put up a photo, or two, to show your WUR setup? I would like to see a schematic, showing how this works, too. Thank you in advance. Tom

Awesome numbers. Here's my dyno with Brian's WUR setup showing the effects of the RPM switch/WUR mod. Take note of the AFR curve before (blue) and after (red). Gained 30-40 RWTQ across the board. The RPM switch delayed boost enrichment until 4400 RPM. After that, the AFR lines are exactly the same

Craig 930 RS 11-15-2006 02:23 PM

David's setup and AFRs are what inspired me to make the leap -
"Who needs EFI?" (Flame on........)

Craig 930 RS 11-15-2006 02:27 PM

Craig 930 RS 11-15-2006 02:31 PM

My charts from last Saturday:

1) See the HP difference from before (red) and after (other colors)?
Still FAR from ideal. Much more tuning needed.

2) AFRs are still funky, but in the opposite direction (lean). See before (red) and after (blue). Ignore the MSD ignition interference spike -

I like, Nice blown six. The engine build is on Rennlist with pics, the engine is not yet fitted to the car but will be soon.
