E85 E85 E85... sigh.
Looks really good! I like how that power curve in the top end just sits there all even to redline instead of diving off.

Is the other plotline a previous power result or is that the pump gas tune? psi?

 

[mrstu]

Thanks hmong. I think 400 hp is a really great power level for the street. Theres not much out there that i cant toy with before pulling away from easily. Its def fun beating up on much more expensive cars with dbag owners.

Gandalf...pretty sure that is one of the earlier pump gas pulls.
E85 is great stuff for sure, I just really lucked out by having a thortons around the corner from my house. There is only one other e85 station in the area about 10 min away in st pete.
If for example the only e85 stations were a 25 min drive across the bridge in Tampa (a much larger city) I'd burn half a tank of e85 getting to the gas station and back while still needing approx a 1/4 of a tank left to get back across the bridge to fill back up again effectively leaving me with only 1/4 tank of e85 range to cruise around with. At the rate I burn e85 it would really suck and limit my use of the car. Just something to keep in mind for anyone considering the switch

That's the reason I'm just going to run 110 on my build. The closest E85 station is 40 miles away from me. I'd be driving 80 miles just to get it so I'd have to buy a barrel or something. I don't drive the car enough to make it worth my time. Great work on the car!

A barrel is a good option or in your case it sounds like you need meth injection.

110 is not what I would want to run all the time and I HATE race gas tunes that require you to drain the tank to use. Way too much effort and too limited for me.

Quick little drive with my new go pro, nothing too crazy...low boost pull running just 17 https://m.youtube.com/watch?v=gn9GLVNy-u0

A couple pics from the ride up to the meet in Lakeland last week

Just saw this thread- very nice setup mrstu. What year is the car? It looks very clean I am guessing it is a lower mileage chassis? What exhaust manifold is that? Equal length?

The car must be a blast to drive. I am forced to buy my E85 by the barrel (not a single pump in all of MT). I pick some up whenever I drive out of state, but it forces me to take my truck every time. We tried getting a group together to buy a bunch, and we had to order 7000 gallons to make it happen. If you buy through a local race fuel distributor, there is a huge markup ($300 for a 55 gallon drum).

 

[mrstu]

Thanks rwheels. The manifold is part of the Blitz turbo kit.

ATS redid the down pipe and wastegate tubing, removed the restrictive sard cat, changed the lines to braided hoses, and welded in a flex
Its better than new now




The car is a Canadian market '93 turbo that was imported by the original owner at the time of his retirement when he moved down to Florida. I still have the original bill of sale and the importation documents. It has a Maple leaf in the doorjam



the 260km cluster


and daytime running lights.

It was completely stock with only 75k kms when I bought it.


It has just under 80k kms on the odometer now. Some would say it was a shame to modify such an original car but I wanted to start my build with the best chassis I could find. The car is still remarkably similar to how it used to drive and sound however.... when not in boost. I've been told by a few mr2 guys with stock exhausts that my car is somehow quieter than theirs is.

 

[rwheelz]

Excellent! Thanks for the info. I am right there with you in terms of starting with the best chassis, particularly when you know you intend to dump a lot of money into the car. I have been looking for the right MK1 and MK2 hardtops for a long time. I bought a 93NA hardtop a few months ago in Calgary and imported it (it was originally from the U.S.). It has (I think) a blown head gasket (80psi on cylinders 2/3), and the paint looks pretty bad, but the chassis is great and has ~100k miles. I have since realized that the 94/95NA was available as a hardtop and adds a passenger's side airbag, so I am trying to find one of those to start with instead.

Your car and build are certainly unique. Does it see any track time or drag racing or is it strictly for street use? What size wheels/tires and how well does it put the power down?

 

[mrstu]

Right now its strictly a lightly driven street car. I've got a '93 TT 300zx with working a/c and a Tacoma that i split daily driving between. For now, the mr2 only comes out at night after it cools down some. As far as tracking the car goes, I don't want to push it too hard in the heat of Florida summer, and I'm still only on 8" rear tires with 245s. I plan on sending my front 17x7s out to be rebarreled to 17x9s in the near future so I can eventually run a 275 rear tire. But traction is actually surprisingly good on the 245s.

 

[Fuzzydunlop]

Sounds reaaally nice. And the AFR's on that dyno chart... wow.

Gandalf, one thing about E85 in a MK1, our tanks are TINY lol! We would be filling up every 100km. Would have to install a secondary tank in the trunk a la Ford Pinto.

Lol, it's where having the ability to switch maps at the push of a button (perhaps re-use the low-octane button!) would be a necessity... and have E85 at home... or a fuel escort

 

[mrstu]

I did opt for a dual tune so I have the ability to switch back to 93 gas if I so choose, tho I'm not quite sure how that works since I only have run e85 to this point

 

[Texas_Ace]

This is why I love flex fuel. Virtually any quality ECU supports it now days. It is cheap to setup and takes all the hassle out of E85. Simply fill up with whatever you have on hand, the ECU sorts out the rest.

 

[ATSAaron]

It is cheap to setup

Wrong.

 

[Texas_Ace]

Wrong.

Parts be cheap, $68.10 for all the flex fuel parts.

Tuning be the pricy part but if you have dual maps tuned anyways then all the hard work is already done.

Not really. While the fuel change is linear and pretty easy to figure out, the timing changes and boost changes don't have to be linear. Case in point we just set the ATS CT27 and ATS CT21 Blackjack records (and obliterated all previous CT records in the process BTW) this week with E67. Yes, you can make it work cheap (but a dual map switch is even cheaper), but to actually optimize it takes a lot of time, blending maps, mixing fuels, etc.

True but I was mostly talking about the parts cost vs tuning costs since more and more guys are doing their own tuning now days.

How'd that work out for you bro?

Tuning was fine, Timing belt slipping ended my build.
