Nice runs and awesome progress! What was your best 60ft. and on what tires? Nothing like beating a big slicked up muscle car in their own domain

Tires are some all season dunlops I believe 205 55 16

the best 60 foot the car has ever hit was a 1.83 . I really believe that it can get into the 1.7x 's with a softer spring in the rear ( currently a 300#)

I was finally able to experience the "black goo" that has been associated with ethanol. I would say that this car has been run exclusively on e85 for the last year or so in a mileage range of approximately 2k.

Fuel system is as follows to recap:

Twin walboro 255 external pumps
-6 AN supply and return
Fuel Lab fuel pressure regulator
Stock 1g Rail
Russel Pro filter -8 AN
Injector Dynamics 1000cc
50 or 55 psi of base pressure

The car was exhibiting very lean conditions during boost runs ( 16:1) . It was soo bad on some occassions that it would not go above 9 psi of boost.

In my mind the only thing that could cause this would be a clogged fuel filter ( previousily this car collapsed a stainless filter). When I opened up the filter there was black debris in it .. This stuff simply came off with parts cleaner.

When I removed the injectors I knew that I had found the culprit



The only thing that would remove this material was 87 octane gasoline. ( acetone and parts cleaner did nothing). After I pickled, soaked and cycled the injectors in a bath of gasoline overnight, I was shocked to see the murky crap that came off the injectors.

After the install everything is back to normal. So I am posting this for those that use ethanol--Check your injectors frequently or run a tank of pump gas through it every now and then-- it could save you an engine. Happy boosting

P.S I hope to build a fuel injector cleaning rig soon that will basically cycle gasoline throught the injectors for an extended period of time.

Ok,
I should read a lot of other posts and maybe I'd find something about it... But what is that stuff?
Might it be seal material which has softened/deteriorated due to the E85? Certainly is ugly!

there have been some lab analysis of the material: varying reports suggest that it is a breakdown of the stabilizer that is place in Ethanol when it is mixed with gasoline.

The seal material ( rubber) or vitton, would come of easily versus this gelatine type goo. It is definitely not seal material

One of the most important things I have read is to not leave e85 sitting in your system for a long period of time. I have had a few buddies lose engines because of E85, I plan on switching to it next year and I have done a ton of research. One of the best articles I have read http://www.injectordynamics.com/AlcoholArticle.html

I sent the injectors to FIC and one of them was over 20% clogged..

I have a wonderful treat coming for the car, this saturday Old School FP3065 , and the car is going back to gasoline, as I feel the car can be pushed to 50+ ibs/min unlike the poor 18g that saw 37psi spikes in some cases,

Pictures to come

Let me take you down memory lane, if you are old like me, then you might remember one of these set ups.. when was the last time you have seen a square Tial wastegate mated to a dsm flanged FP turbine housing .. these gates are so bad ass that you don't even need a gasket because the mating surface is set up to a higher tolerance..the precusor to V-band wastegates.





This is the hot side for the FP3065, I basically cleaned it up a little, as it had 10 years worth of dust and grim caked on to it. Notice the very cool, tubular V-band o2 housing that goes to a stock downpipe location, which was pretty "Hi-tech" for 2003.

The turbo wheels impacted the housing due to oil starvation from the previous owner, so needless to say, the "scrapes" willl need to be sanded down and blended.


ETA on center section is saturday.. The colt is going to be able to stretch its legs a little furthur.

New center section for the 3065-- Look at the size of that compressor wheel


We soaked the compressor cover, back plate and some other pieces of the assembly over night, so that we could get more grim out of it


all assembled




Did some fabrication work for my friends 60s volvo... QA1 end links on some tubing for his rear control arms. This has me thinking about another side project for the colt--on making a quality rear control arm to adjust some of the camber issues that it has.



Just a few more fittings to buy and it should be ready to bolt on

More later

Been a shitty weekend of being ill, but still have to finish up the work for the customers. Jeremy and I still had a few hours to screw around with the colt.

Here is a quick graph of the last pull with the 18g on ethanol with boost a little over 30 psi and afr around 12.20s


Next up, ordered all the fittings and lines and gaskets for tHE 3065 , sitting in the bay looking pretty




My son is obsessed with this show called "despicable Me" and if you have watched it , the villian in the movie called "VECTOR" one of his favourite sayings is "OOOOOOOOOOOOOOOHHHHHHH yeeeeeeeeeeeeahhhhhhhhhhhhh"

That is all I can say when I see this turbo in the engine bay

enjoy

Piranha Gun!!!

Badass looking turbo setup. You are going to tear some things apart, and all of it will bring a smile to your face.

Nice!!!!!!

Jeremy and I did a little more work on the colt tonight, welded up an intercooler pipe and buttoned up some things, we still need to attach the exhaust and add some t bolt clamps amongst other tid bits, but I love how ball bearing turbos sound once you shut them off enjoy ,, we sure as hell did
http://www.youtube.com/watch?v=RBFsMTfrhqE

and we need a new filter ... that thing is hit
