EV1150 LT4 power package vs. 416CI, Cam, YSi
So we wanted to get a real world, back to back, hot run comparison of our LT4 EV1150 Package. Same dyno; each car 3 x runs back to back, within 15 mins of each other.
Car 1- 2016 M7 1LT ZO6 with EV1150 Turbo conversion. Stock heads, stock cam and stock bottom (19.5psi max boost)
Car 2- 2014 M7 2LT Z51 Stingray with TSP 416CI motor, YSi supercharger with 2.30 Griptech upper, blower cam and meth (22.5psi max boost)
Guess which line, Red or Blue is which?

I am sincerely interested in why our community seems so averse to single turbo systems, even when they are half price or less vs similiar power level supercharger builds?
I’m a blower guy personally, but in the right car with a well thought out combo, a turbo is hard to beat. The boost looks like it hits hard and is much more efficient making power than a blower. Heat management and custom fitment requirements are usually what make blowers the simpler solution. Just my .02.

I did forget to add that both cars did 3 x back to back pulls so no cooling or tricks to get cool. Air temps were 65-67*
You asked why people are averse to the single turbo systems. I'm in the process of collecting parts for my vette. I can share the reasons why I ruled out a single turbo system, even though it is the most cost-effective way to make 850+ rwhp .1) the install of single turbo systems with all of the header pipes running up front does not look as clean as any of the blower options or twin turbo systems. It simply does not look OEM, if that is important to a person. 2) I know this has been proven to work and be reliable, but I simply do not like that much hot piping in the engine bay around all of the components.
^^^ true BUT then again ANY thing you do to a car to improve what ever in it power r what ever has it's draw backs also. You can power coat the hot side then also wrap it also that will help a top on the heat..
I wish he had this kit out before I did the blower set up on my car it would have a turbo on it now for sure... Robert

Yep you guys are correct. It definitely does not look as standardized as a centrifugal kit but it definitely draws much more attention than a SC. We put alot of time and testing into producing this matched package but it is definitely hard sledding even though the price point and efficiency are far superior

Oh absolutely you're right Robert. It's just the blower guys (ECS,A&A, ProCharger) were johnny on the spot 4 years ago with a simple clean kit and any good DIY'er could put it on. Think about it, a guy can buy a stingray and put a $5000 blower kit on it in his garage with zero fueling changes and make almost 600 wheel.

This is a good point. Remember a turbo makes about 30% more power given same conditions. We made 842 whp with port injection and no low side fuel changes on a stock LT4. https://www.edgyvette.com/product/ev...power-package/
We could easily make 700whp on E85 without any front or rear side fueling. Just a much more efficent system. Base PTS ST kit is around $6k and you dont need CAI, headers, and other bolt ons like you do with a SC kit. By the time you add other needed mods for the SC system you are $1.5-2k more than the $6.5k single turbo and have less HP and TQ.
Fear of change, fear of the unknown factors in. It's human nature to avoid those things you do not fully understand that can hurt you (or your wallet) due to that lack of understanding. SC's and vettes have been around (with a lot of aftermarket support) a lot longer than turbos and vettes. It'll take some time, but people will come around. Just my 2 cents, it's a statement of my opinion and not a statement of fact.
Im interested in learning more about the turbo setup. My initial concerns would be around heating issues. Putting hot headers and a hot turbo all in the engine bay must cause some temperature increase.
Do you have any real world results from a drag strip or track in terms of temperatures? Temperatures on the dyno don’t feel real world when you have the hood open and fans blowing on the engine bay.

Look forward to learning more about this setup.
We have about 11000 miles on this setup (2016 ZO6 M7 EV1150 conversion) mostly daily driving and WOT pulls at FL2K and similar roll race events. Car went 142mph in the rolling 1/4 mile in 2300 DA and on 16psi which is about 900whp. We do not drag race the car from a dead stop so no 1/4 mile times. More rolling 1/4 mile and 1/2 mile times coming in the future.
While the dyno may not replicate open road conditions I would submit that open road conditions are almost always more beneficial than dyno conditions in a closed building with fans blowing; hence the reasons most tuners road test a car after WOT tuning on the dyno. A greater volume of oxygen and greater speed of intake air flow may require pulling a little timing. In truth I was completely surprised at how much stronger this single 82mm turbo on stock LT4 long block was vs. a 416CI, cam, YSi car on 3 lb more boost. There is just no comparison when it comes to supporting mods needed to make power with each system and the cost, including install is MUCH less also.
Our other shop car (Yves 17 M7 Z06) has the EV Xpipe, EV ported snout/w 2.30 griptech upper, EV ported LT4 TB, E50 and direct port methanol. Car put down 670-680.
EV1150 car coolant temps run about 10-15 degrees higher than 17 Z
EV1150 oil temps run about 20 degrees higher than 17 Z (Turbo is oiled by engine oil)
EV1150 IAT temps run LOWER than the 17 Z
Objectively this package is VERY efficient; gaining 40-50whp per PSI under 900whp and 30-40 per PSI over 900whp.
