I am having a good time

I am on the break in map - still trying to get rid of all the pump gas awaiting the E85

A few words - I note the genius like tune of Sam @ By Design and how my car runs just like stock with ID1300 injectors and these bigger turbos and turbo inlet tubes

Start up and idle is exceptional

Oddly - my gas mileage has improved - not sure if that is related the spark plug and coil change but I am getting significantly better gas mileage - not that I care - I am actually frustrated trying to get rid of the pump gas as quickly as possible

These turbos even de-tuned give a lot more power on the top end as I am driving them more I am seeing how they flow a lot more air after 5500 to red line than the stock ones while the stock units can be pressed for peak power they will not pull and hold boost to red line like these do a different feel to the car

Next up E85 - went to the station to fill my gas can will drain the tank and then its time to turn up the wick a bit

 

Thank you I am trying to contribute back to the forum as I have found a lot of great info here

One thing additional thing to note - with the turbo wheel change the EP1 is now called the hush puppy = need the EP2 for sure

It is amazing how the wheel change really effected the sound

The only sound I hear now is my rear tires attaching the pavement with brutal force

I am enjoying the new found power

 

08957 glad to see its back on the road and working thru the 93oct to get to the e85 fun. I know you have played around with e85 in the past so you have an idea of the power increase coming. I expect you will be pleasantly surprised the power this platform can achieve with the bolt ons you have

Not sure exactly when you are swapping exhausts but as you can imagine if you guys dial it in with the EP1 I would highly recommend re-tweaking the tune when you go EP2 or whatever higher flowing exh you choose. The base tune will run better on its own but there will be more on the table at that point to keep pushing (safely).

Yes some fuel economy could be had because BSFC has improved from the drop of pumping work and more open vane position. And of course the plugs and coils being new will help with optimized combustion. I believe the calculation on the dash is now off because of the injector swap so its not exactly what is being displayed but the mpg is pretty good for a 700hp car on 93oct . As you know and expect there will be a hit on mpg going to e85 but worth it in my opinion

The sound (from a turbo perspective) will change no doubt. From a turbine blade bypass we are now running at a different vane position and different turbine wheel tip speed. This will have a strong affect on sound.

 

Much appreciate your insights as usual

I do think the distance and mileage estimate on the dash are being thrown off big time by the very small IDC that I am running

However, regardless of this - I am really taking much longer than before these mods to burn through a 1/3 of a tank of gas

Before I did these mods when I was squeezing the stock turbos I was literally flushing gas out the back of the car

Now the car is really having a hard time to burn up the gas in the tank and at the same time going significantly faster

I guess these are some desired side effects :

Significantly more power and better power band

Much better fuel efficiency

Much more quiet and better exhaust tone - sounds more like a tiger and less like an angry kitten

 

lol that's .

Speaking of improved mileage, I was surprised that I seem to be getting better mileage with my new turbos even during "datalog days" where the car is repeatedly run to redline. Maybe I'll have to drive this way all the time, you know just for the sake of better fuel efficiency.

 

not sure what mileage improvement you guys are talking about, my PCM is showing 11mpg with my 1300cc injectors on the pump tune. lol

 

Another word to the wise when you are running E85 and 1300 injectors. Do not believe the miles left per gallon or gas tank reading once it gets below half tank. If it hits the quarter tank mark, fill up immediately. Ask me how I know

 

Nice to see the build progress. The car should be a blast with those turbos and other upgrades.



Either you are at WOT a lot or your cylinder walls are getting a nice wash.

 

you have to occasionally take your foot off the loud pedal.

I used to get 400km per tank of gas but lately I've been getting 425-450km per tank even with the datalog runs. No complaints.

 

+1 at 1/4 tank i start looking for a gas station,i actually keep a couple gallons of E85 in the frunk just in case,it's weird though as sometimes i'll run out on just under a 1/4 tank & other times when i fill it up it only takes 12 gallons (so theres's atleast 5 gall left) i think it depends on how spirited of a drive you've taken .About the only downside of E85 that i can think of.

 

That is weird, as I drive mine right down to the light and past sometimes and never ran out of fuel.

Watch I said that and this week I will be posting that I ran out of fuel at 1/4 tank!!

 

Yep. Same thing happened to my brothers car. Read 1/4 tank, shut off on way home from vacation. Luckily I was traveling with him and had to go find gas. Lol

 

This can and should all be calibrated for different injectors and/or fuel pressures. There is no reason why you should guess the remaining fuel and when you run out of fuel before the tank low light goes on, you shoud talk to your software supplier.

Properly calicated the remainung fuel is 8-10 litres after the fuel level low lamp goes on. A little difference is ok, but you should always be able to trust your fuel gauge.

Regarding Forge products: these are highly overrated. My personal experience is like this. BOVs: stuck. IC: suck. Hoses: F... err fitting problems

 

I may be wrong but I thought Cobb had some update for the fuel level measurement error? The file I use with my 1kcc has been fine, I can run way under a 1/4 tank it has been fine.
