You make great points and I really have no argument against. I typically try to do things right the first time when modding the car. However, it's also my hobby/toy and am constantly adding or trying new things as I desire. It's not really about the money or being economical, but more about what I want to do and when. I also enjoy doing the majority of the work myself or with my dad on the vehicle. It's my release from being CEO of a company and having a wife and 4 kids. So it's possible I go E-85 down the road, but just really have no desire to do it right now.

Not having to run your tank to near empty anytime you want to switch fuels is the downside of uprev, having the ability to run a mixture of both fuels and a gauge to tell you the content and having the ecu automatically adjust timing according the the E content is worth the extra time and trouble of the install. Putting your hard earn time and money into something done right the first is a must. Plus staying NA and not have a supper aggressive map you could probably get away with it and be fine.

Additional Quarts 1 Quart

Starting the tear down this weekend. Hoping to have the car delivered to @Dynosty by the end of the month for a re-tune. In addition to the JWT C2 Cams, since laying down the 341whp/271whp I have added the following:

-Z1 Ported Lower Intake Manifold
-Z1 Race Intakes from standard Z1 Intakes
-Z1 2-piece lightweight rotors
-Dewla Intake Guide

Trying to keep my expectations in check, but would be really excited to eclipse the 370whp/290wtq marks. Would put the HP per Liter around the 118 mark in between the Audi R8 (117.3) and the Ferrari F12TDF (122.2) which are the pinnacle of N/A Engine benchmarks.

also just be aware you need to pull the transmission and the secondary oil pan to get to the oil pump out..

Just as an FYI, this does not appear to be the case on my car.

Yeap, you have to pull both. Seb didn't lead you wrong.

Random aside, didn't the S2000 make 120hp hp per L? 240hp, 2.0L F20 engine

That is correct it did, and stock. The list I checked were for current production models, which in all honesty makes the F20 feat even more impressive.The highest current HP per Liter N/A engine is the Ferrari 458 Speciale of 132.7.

Regardless, rarefied air as far as N/A engines go.

production engines only right? I know of more than a few spec race engines that do well into 150hp/l

Look at motorcycles. They're over 200HP /Liter.

yeah but that's an economy of scale thing once you start getting to 2.0l high output engines the mass of the components at the larger size and to handle higher dead torque loads prevents you from spinning the engine 12k+ rpm easily look up the stanton racing engines sr11 midget motor. roughly 380hp from 2.5l NA
