less than 12:1 CR, STOCK valve sizes in STOCK head castings and built legal to SCCA E prod rules.

We detuned the combo purposely, with more CR and cam I am positive that this combo could tip the scales at 220+ reliably.

I made this power on the FIRST dyno pull with default settings. Specs of the build that we can share are over on my forums.

Kevin Groot is one happy man, all of us here are as well! Thanks to Kevin for believing in me and my Employee Blake Meredith for his assistance
in getting this project wrapped up after so many changes were made and meeting the deadline for Kevin's first race in late March!

An engine of this level is a different world.. It has well over 400 hours into it and most of that wasn't assembly. I take on VERY few engines like this and by far these are the most expensive engines we can build due to the parts the rule book forces us to use as well as the limitations we have to overcome.

As far as quoting a price, an engine like this one can't be estimated, it can't be quoted... Matter of factly I lost money on this build and it was still expensive, BUT the development and data we attain far supercedes the profit on a project like this.. These engines are our version of the "959"

We are in the process of standardizing all the performer and daily driver series engines for purchase online with a limited amount of customization. We have just now gotten development to the level where we can offer 200HP street engines at known prices. These will be available online through the Type 4 store in just a couple of months from 2056cc all the way through 3 Liters.

No, conventional lifters. The roller cam is illegal along with 85% of the other things we generally use to make this level of power.

I am looking forward to the engine packages on your site, that will be great.
I just got the extra cash together...so I hope what i need is all in stock...woohoo..

Question Jake, for one season, do you think a 2.0 liter piston with a shaved top would last? by this I mean shave off the top of the piston to make it flat, flycut the heads to get the c/r back.
If I need to re-ring next year, fine.
I will probably build a fresh 2.0 liter next year...just want two motors this year, and the big one is where the money is heading.

The top ring will really hurt.. The top ring on the stock piston is one of the first failure points...!

Today 200 HP is a common occurence here, the last 3 engines we have completed have hit the number or exceeded it... The next 3 should also make the grade, except a 1500cc Land Speed engine that I'll be finishing next week, its a measley 165 ponies but holds 3 speed records!

200HP from 2 liters limited with the rules we have to work with in E production is a huge feat, especially on our first attempt with an "E" spec engine..

300HP.... Well lets just say that by the end of this summer we'll be really close to that number if things work out the way they are shaping up.. It won't be from a 2 Liter engine, it may have started as a 2 Liter, but it'll weigh in at 2.7- 2.9L to attain the big power and on pump gas!

Brer, The 1.7 is a great engine.. They are the most resilient Type 4s that one can create, the term "Takes a beating and keeps on ticking" applies!

Any chance you could post a sound file (or video) of what the motor sounds like at 7500 rpm?
