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

Green is the baseline before the changes. Blue is after on 91 octane and red is on E85

oh man im pumped about this no offense but are you missing anything compared to the guys doing 370whp with these cams, just wondering because i had e85, seb tuned uprev on seb's dyno and was 20+ higher than that with the full Na drysump build. don't feel bad though that car wrecked me financially for 4years.

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

:iagree:

The smaller the motor. The more HP/liter. Try and get a 7 liter motor to 200/liter N/A. :rofl2:

Yes I’m on 4.08 gears going back to stock end of year and going to dyno for numbers.. should be in the 370whp range

Nope building another unicorn instead. Debt free this time so who knows when it will be done this ones full stupid tho. It will be running jwt c11 or c12 cams though. Its not to the point of build thread yet.

Getting closer to the actual install of the cams. It has been a bear, but will be worth it in the end. I'm sure putting it all back together will be easier than taking it all apart. Been good bonding time with my dad and I anyways and given him something to work on in retirement. Hopefully loaded on the trailer and hauling to Dynosty in Louisville for a tune sometime in the next couple of weeks.

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.

It may be the case if dropping the engine. However, we just disassembled the oil pump and it came right off. Pictures below.

Ah, you took the whole front cover off when you installed the cams. This is what allowed you to twist the oil pump and pull it off. Most of the time you would hang the motor from a cradle and pull the rest of the oil pan.

Here are some more pictures of our progress. The tear down is a bear. Only thing left is removing the springs, then the rebuild can begin and I believe will move much quicker than the tear down. My dad has done the majority of the heavy lifting, he has no VQ experience, but has built drag and circle track race engines his entire life. His claim to fame was that he was Terry Labonte’s engine builder before he made it to cup, my dad is from Corpus Christi, TX. The VQ is definitely a different animal but he is really enjoying the work since he is retired and doesn’t have a lot of other exciting things going on. Patience is a must if doing this install to do it correctly. A lot of notes, pictures, cleaning and replacing everything preparing for the rebuild.

I’m just struggling with the patience part, can’t wait to see what it can do. Hopefully by the end of June.

Great tear down pics!
