I am not a fuel expert by any means, you can call bs if you want, however, if different vendors that I have talked to says that e85 will eat regular fittings and rubber lines, then I take them at their word as I do not want my $50k+ motor destroyed. I have heard of a few e85 fuel system failures, I'll have to do some digging to get some examples, maybe some vendors will comment.

As for pcar tax, this is simple math. Lets compare your examples, lets say it costs x to develop a part, with the pcar you are amortizing your costs over lets say 100 cars for example, with your examples you amortize costs over 1000 cars. We are lucky to pay only twice as much as opposed to 10 times more. You have to pay to play. As for pcar, they are mostly affordable in comparison to lambo, ferrari etc.

 

By no means am I attacking you brother. Basically I would be attacking the comments of whoever told you these untrue stories. I'm just trying to bring up your awareness on e85. Ive had plenty of cars that I feel the tax on parts that are necessary.

 

Agreed on the "pay to play" thing however when speaking about just E85 swap what type of parts would be needed that are completely specific to Porsche or Porsche 996 Turbo / GT2? If we are just talking about fuel related stuff then most of that should be just off the shelf....correct?

 

Should be off the shelf-misc. fittings, filters, fuel lines that are E85 compatible (most are) and make sure your fuel pumps and regulator are E85 compatible.

When I did the fuel system on the Supra back in 2005 I made sure that the lines I used would withstand methanol, which is more harsh than E85. Everything else in my fuel system is standard fuel system stuff-anodized fittings, the pumps are standard Walbro pumps (3 of them controlled by the standalone), etc. I didn't have to change a thing when I went to E85. The PRO EFI standalone has flex fuel built into it, which controls the fuel/timing/boost level depending on Ethanol content on the fly.

Ive done a good amount of research on e85 builds now as Im looking to do one myself. As far as 996 You will need a fuel system. On 997tt if you run e85 on VGT's you can go off your stock fuel system, if you want to go bigger turbos its gonna run 5k as you will need a bigger fuel system. Sucks, but these cars arnt 30k msrp jdm cars. It seems like from what Ive heard tuning is the most important thing with the e85 build. Protomotive seems to be doing 75% of the e85 tunes out there i think (switzer the other 25%) Jus going off of all the people ive spoken with.

 

E85 is good stuff. Tuning is important. The whole fuel system does need to be reworked to be able to supply enough ( 30% more fuel) and feed the larger injectors. Reworking the fuel rails is not a bad idea too. For pumps you can use 3 044s if you want over 1000whp on E85 or a Weldon 2345 single or I heard FueLab makes a nice one too for 600$. Good fitting and hose will set you back a good amount too.

 

I don't understand why it would be $5K for a fuel system? You've got pumps that will run $500-$600 (depending on how many you need), fuel pump hangar-maybe $400.00, injectors that will run $600 (PTE 1270cc injectors/120lb-enough to supply 850whp of fuel), fuel lines-maybe $200.00, fittings-another $200.00 tops, fuel rails ($300.00), fuel filters ($250.00 or so) and a regulator ($150.00). That's $2500.00-$3000.00. Where does the extra $2,000.00 come from? Install costs?

I am doing mine and the line and fittings are more then what you say. At least for the Aeroquip parts.

and install is a good amount of change as well.

Its been said lots of time here, the R&D part is expensive on cars that are not Hondas

 

I didnt have proto or bbi give me an itemized list with the price of each part. Im just going off of what they told me. im sure labor is included in the 5k. When I pull the trigger on the build I'll get more into detail.

 

yup instal is the rest steve. it take a good amount of time .

 

Fittings alone will be +/- $500. The more pumps, the more $$. Regarding the Fuel lab pump, i have tried one and didn't have good luck. Search the web on that pump before you buy.

 

I run 044s...

 

Good choice

 

+1 well = 3

 

your setup will use 3 in parallel, all in-tank?
