Can't remember the status on the other ignition driver in that box. I know at least one was totally fried, and I jumpered it to make for a TTL output to trigger the stock coupe coil setup.

Open 'er up and look!

Might take a peak this weekend.

Small update:

Passed Air Care Colorado E-test! With a "Fast-Pass" no less!!!!!

Now I am good for 2 years. Hopefully the drive by program will still be around. Load a clean file & drive by the truck a few times. DONE

Amazing what a little E85 (3/7ths of a tank) and a fresh kitty will do.

It is running pretty well on the 4:3 91OCT:E85 ratio after a slight tweak. Might leave it this way and do a little leak fixing before swapping injectors and going 100% E85 + boost.

Nice and clean

HMmmmm

Interesting, be sure to get some good pics up, haven't seen that style before.

Just a sketch of what smoking would look like. I have a theory that nightshades might work over chrome. Going to have to get just junkyard chrome to test.

The H1/H4s do not leave anything to be desired. I bought a bucket with tabs to fix that issue.

Just toying around with saving the real lights. Really I should be buying a bumper to mount an intercooler behind.

Really cool that you picked this car up.

Looking forward to watching it progress :-)

Any tips on configuring the Turbo/Engine Flow Calc for E85?

Step 1 will be tuning for 50/50 E85 (so 9.25G of E10 + 9.25G of E85= 8.7875G E100 + 9.7125G 91OCT= 18.5 G of E47.5 @ ~ 98 OCT)

This will be an intermediate step before installation of an Intercooler.

leave afr normal in calc think lambda. 12-1 afr @ .55bsfc or 11-1 afr @ .60 bsfc. is reasonable

Educated guess 11-12 psi will be needed to get you back to sea level numbers. With ethanol should be able to beat nates dyno numbers at that 11-12 boost uncorrected

Mcstiff · **Posted:** Sat Jun 20, 2009 9:40 am

I was working under the impression that lambda for E85 = ~9 AFR. Value updated.

Just looking at the T3-60 map to see where it runs out

Need to get a WBO2 in before much more happens with E85.

User "Hotrod" on NASIOC thinks TC's E85 BSFC is .65 from .5 or a 1.3 correction. Formula SAE uses a factor of 1.4 to correct unleaded BSFC to E85. I hope they are doing more then guessing. I'll go with the SAE for now.

Bell cites an injector size formula of (Goal BHP*BSFC)/# of cly= #s/min of injector says that (240 bhp*.77)/5= 36.96 #/min * 10.5= 388.08 cc injectors.

If I have 42# injectors as noted on the previous dyno sheet then:

BHP= (inj x cly)/BSFC = 272.7 So, on paper, 42# injectors should max out at ~ 272 BHP with E85.

Nate, does the CQ have the 42#ers noted on the dyno sheet?

newt · **Posted:** Mon Jun 22, 2009 11:12 am

Negative, it has the stock replacement injectors, running at 4bar, so they work out to nearly 40lb or so.

Mcstiff · **Posted:** Mon Jun 22, 2009 12:19 pm

Cool, I guess I could have just looked :wink:

then I would have to open the hood and maybe turn a wrench :lol:

Playing with another plotter:

T3-60 12 psi E85 no IC

The multiple points are nice but it seems "off" idk

Mcstiff · **Posted:** Tue Jul 14, 2009 12:39 am

For the record, S2 xmember and IC "under" a CQ bumper.

I think a custom xmember and maybe a vertical flow IC would fit better (aux raid delete and some ducting and trimming).

Hybrid_Hatch · **Posted:** Tue Jul 14, 2009 12:51 am

Thats actually a 3b intercooler... but yeah...

Mcstiff · **Posted:** Tue Jul 14, 2009 1:13 am

Lets just call them S2 parts

Found this example too:

Not perfect but closer to what I am thinking.

jitsu303 · **Posted:** Tue Jul 14, 2009 7:42 am

Or you could get a S2/Euro Cabrio bumper?

Mcstiff · **Posted:** Tue Jul 14, 2009 8:59 am

Is that a question or a statement?
I have been keeping my eye out for a red S2 bumper but have not been able to find one. If I have to paint a bumper/bumpers then I may as well respray the car.

ICing is a higher priority then looks and the above options do not lock me into anything (I can get a EUDM bumper when I find one). Function > Form.

jitsu303 · **Posted:** Tue Jul 14, 2009 10:54 am

More of a statement I guess. I have a EuroCab bumper I don't need but it's a gold colour.

Mcstiff · **Posted:** Tue Jul 14, 2009 11:08 am

Early or late Cab? IIRC the cab bumper does not have much room behind it.

BostonCQ · **Posted:** Tue Jul 14, 2009 11:54 am

There are a couple of downsides to my approach- cost and cooling. Getting the custom fabrication for that intercooler setup cost me around 1.5k. I can double-check that figure. The engine also runs pretty hot. Make sure you have a good radiator/fan setup and appropriate shrouds.

Something like this (took a while to remember I had a pic):
