We have been making well over the 400 mark on cars with a Blend Tune lately

I would say on a dynojet 335-340 whp and 390-400 wrtq I am thinking it will be about 10% lower than that on that mustang dyno. We will see. Your coupe fully bolted on the stock turbo was trapping 3MPH higher than the sedan IIRC.

the 4 door seems to like the full E right now. Its really likes the TF tune I have on there too. Pull wise I can't really tell a difference.

I am not battling any tuners, everyone I have dealt with is really good. (Other than superchips)

Why not just get a real turbo and make some real numbers?

Trust me man, if you don't want to stir up any trouble, I would not post a comparison test of Trifecta vs. HPT E85 results.

Its just going to start the whole Trifecta HPT battles again that are never ending between people.

I guess 367/424 on stock turbo isn't real enough lol. Look at the dyno list and how many big turbo cars didn't make 400whp. Not to mention, the car is already worthless traction wise at this level. 3rd gear just laughs at the pavement now..

I drive a bit out of my way to fill up BUT if you do a blend tune it will last a decent amount for you. We saw minimal gain going from 1:1 to 2:1, so you could really make it last with a E30 blend and still get the power boost

Stir it up.. I haven't seen any TF customers post a over 360whp graph on E like we have.

its all in how much time is put into the car too. Some people don't get their car fully dialed in by vince and just throw it on a dyno.

I guess reading fails you, check my sig. I don't need a car with a "real turbo." Also I am all about research and development for the community, I am not all about dyno numbers, I am about the whole picture. (1/4 mile times and drivability.)

I am curious to see what Drews 4 door puts down on E-85. The torque limit on E-47 appears to be approx 430 wtrq (on that mustang dyno anyway). I still see no advantage going above E-47 in most cases.

Because ~400 whp and 430 wtrq on a mustang dyno and a powerband from 3K-past 7K RPMs is not an improvement over stock? He already has traction issues in 3rd gear in 100* dessert heat at 3,600 ft above sea level.

We made 447wtq on a couple pulls with a Eblend car.

Yeah the only real advantage to running full E is to be able to pump just once when you gas up and to minimize the fluctuations in the mix that you may get from fill up to fill up.

I do not know why, but the powerband seems to be better on a full E car with little mods.

Sorry but the torque limit on E-74 no what you do with the injector constant, rail pressure ramping and injection timing is much lower than your car was able to make on the stock fuel system. Your car made 240 whp SAE stock on your mustang dyno you posted the dyno sheets right after you picked the car up. So if you take that 10-12% difference that normally exists between a dynojet and a mustang dyno your car made 264-270 whp SAE stock on a dynojet?
1. My car doesn't have to be magic. We learn new ways to make more power. That is our job. I notice that you ignored my statement that I trapped 119mph right after I dyno'd 356 on our dyno.

2. Yes, I have seen stock LNF Cobalts make 260 on Dynojets.

3. Now you are stating that the difference between Mustang and Dynojet is 10-12%, but you have simply moved into the next topic that you still have a lot to learn about. As I'm sure you know, Mustang dynos require vehicle weight to be entered. You may also know that the number that you enter affects the hp numbers. Because of this, lighter cars do not take as much of a hit on a Mustang dyno as a heavier car. While a 4000 lb car might lose 10-15% by going from a Dynojet to a Mustang, a 300 lb car might only lose 6-10% This is something that is rarely discussed, but should be.

Different dyno though. That is why I put in parentheses on that mustang dyno.

Did you try E-47 in the 4 door first? Or just strait to E-85?

Another thing that people have to realize is that we know how to get power out of cars on the dyno. Similar to what is commonly known as the driver mod, it works the same way on the dyno. It just is what it is.

This is true. I wish I could have been doing the driving for my dyno pulls.

The dyno I was on you enter in the weight of the car. Anyways, the car will be dyno'd on the same dyno so I can see what real world gains I get.

That and he used 4th gear on the pulls. Although we have no perfect 1.00 : 1.00 gear fourth is technically an overdrive gear at 0.89. Third gear is 1.19 so neither is perfect but I like to use 3rd gear. When you do the sedan ask him to do both fourth and third gear pulls to see what the difference is.

I've done 3rd and 4th gear pulls and saw no difference in power at the wheels. I found it odd.
