Fran seems in a better mood lately, and when he is in a good mood he shares more of his thoughts and knowledge, it benefits us, the viewers. On a side note, what an amazing platform the C6 corvette is. It is a beautiful design that is affordable, and very easy to modify for great power gains. It will probably go down as one of the very best car enthusiast platforms we ever see. It is a performance bargain, and the chevrolet engineers in charge of the C6 did an amazing job. Props to them.
Since the camera guy falling out, this video has a much happier/cooler vibe to the shop! Good to see everybody getting along, producing great cars , making money and having fun!
I'm not taking sides, I'm a casual watcher and don't know any of these guys personally. To the casual watcher like myself, the vibe on this video is significantly better and more fun to watch than many of the old episodes. When you produce cars this cool, you should be having fun!
From what I’ve learned with running the kong 2650 on my SBE ZR1 with 2 different cams and 4 different pulleys is that they become very inefficient with boost levels above 23+psi. The 2650 starts hitting a brick wall the iat2 temperatures start rapidly raising due to not being able to get the air out which will drive boost psi up. The sweet spot for the 2650 is right around 18 to 22.5psi of boost. Seems like a lot of the Strokers 400+cid make incredible power above 1100+ rwhp around 18psi to 20 psi with 10:1 to 10:5 compression ratio on E85. I’ve also learned the factory ZR1 mufflers are restrictive at these power levels with them removed you can drop 1 pound of boost. On E70 fuel with my old cam (228-242 .604" lift/.622" lift 117lsa ) and running a 2.40 upper with 14% lower made 1027/1001 rwhp/rwtq SAE making 25.4 psi of boost. Also note the power would start rapidly nosediving after 6500 rpms. We went to a 2.625 upper pulley and made more power 1041 rwhp / 941rwtq by removing the factory mufflers and dropping the boost to 22psi. The Power also carried all the way to 7200 rpms. We then did a cam swap to a much larger Camshaft GPT stage 4 and made 1063 rwhp / 947 rwtq SAE with the 2.625 making 21 psi of boost with the ZR1 mufflers connected. Next we tested a custom 2.50 upper pulley and made 1071/976 making 22psi of boost. Then tested it with a 2.40 upper making 23+ psi of boost and the power did not carry the same as the other two pulleys. it started falling on its nose after 6800 RPMs versus with the other two pulleys power would carry strong to 7300 rpm's. Final numbers with the 2.40 were 1069 rwhp / 995 rwtq SAE. To take advantage of the 2.40 would need to run a bigger cam to slightly drop the boost. we could’ve dropped the mufflers as well but decided not to since the car is driven with them on and our last test proved that dropping them does drop 1 pound of boost. I guess ideally you could install cut outs but really not a lot of room underneath to do so on the C6. Just wanted to share my results awesome video guys incredible build on the ZR1! 💪🏽
@@donls1sscme Oh you're the one who got it? Big congrats man, that is an absolute animal of a zr1....... Are you planning on posting any pulls? I will definitely stick around on your channel if so!
Question , when yal install a Kong air filter or even k&n carbon air filter on c6 ZR1 do yal cut out the hood vent honeycomb looking thing or air dam so more air will suck in from filter ? Cuz on my zr1 it looked pretty closed up Thanks
Frans attitude is completely different now that Steve is not trying to talk for him!!!!! The guys in the shop are warning up to the new camera guy and things are getting better. Let’s see more dyno pulls and less chatting about nothing. Put the dyno numbers up on the screen, that zoom in on that white background is hard to make out without stopping the video and zooming in on it.
I h ave an 07 Z06....H/C/I....570 wheel....Car has 60 lb injectors 11.5 compression and a walbro 450 fuel pump ...Bought the car this way.....Would it be beneficial to add E-85 ? I figure I have most of the parts .....Would need of course a flex fuel sensor because I can't run E85 all The time.....
I called up there to get a quote on truck project guy told me y’all wrk on cars 16’ and newer so why I see shop full of c6s I feel it’s a bunch of bullshitt honestly
@@RaceProvenMotorsports yeah that’s understood but who ever answer the phone chuck charles Charlie watever his name is was rude as hell I get if newer cars are easier to tune and wrk on but kinda bugs be out that on previous episodes y’all have wrk d on older cars so you guys just made this change with in last year or so

If you watch the other camera guys video Fran is a dick to work with. Make you work during lunch with no pay wtf
@@markcasto9526 yeah, I always saw that tension throughout the shop. But hey, who am I to judge?! I'm sure they both have their sides

This was all on stock bottom end correct?
You guys build some of the baddest c6 zr1 and c6 zo6 I've seen so far!🔥
Love seeing Fran get excited about a build.
Starting to enjoy this Channel again, the camera guys laugh is pretty exotic lol
I’m glad to see that everyone haves good vibes and that the videos are starting to look better😎
That vette is so sick🔥crazy hp! It's so exciting seeing my car in the background patiently waiting for her turn🥰
Wow! Super strong C6. Like the new camera lens. Keep em coming gents!
That black beast is perfection. Nice work guys!
That black ZR1..... dream car, dream build
that ZR1 turned out fucking nasty, hope the owner has a tire for it.. my ZR1 will be headed your way in a few weeks
I miss seeing Fran’s ZR1 hurting feeling without the nitrous lol
I have it now in houston ... got a brand new set of rear tires going on it in a few weeks
@@donls1sscme Oh you're the one who got it? Big congrats man, that is an absolute animal of a zr1....... Are you planning on posting any pulls? I will definitely stick around on your channel if so!
Nice video good to here Fran explain the technical part of the builds
That black zr1 is a insane build
Really enjoying these videos, big change in you guys now, more fun.
Great job fellas….. great start to the weekend!!!!!!!!
Reading very quickly, I thought the title said Stage 8 ZR1 so I clicked super fast.
seems like everyone in the shop is much happier
That black zr-1 was crazy!
That guy better go with a different wheel / tire combo or that car won't last if he starts getting into it 😂
Great show guy’s 😎🍺👍
Awesome video. Ideas for future build 🤔
That ZR1 is one sick bitch. Great job.
What do you guys dislike about the alky meth kits? I’ve heard nothing but good things about them.
With that valve tran what were you spinning the motor to?
That ZR1 is sweet! Not a big fan of the chrome wheels, but awesome otherwise!
How that map sensor hold over 23psi on c6 Zr1. Cuz mine won’t
Question , when yal install a Kong air filter or even k&n carbon air filter on c6 ZR1 do yal cut out the hood vent honeycomb looking thing or air dam so more air will suck in from filter ? Cuz on my zr1 it looked pretty closed up
Thanks
No we don’t touch that. It won’t help one bit.
@@RaceProvenMotorsports
Ok cool
Thanks
You guys build some bad cars! Love the work! Why do we not have any e85 at any gas stations here in Delaware? Just curious if anyone knows.
Delaware passed some law that states gas can’t contain more than 10% ethanol. I guess they forgot to exclude E85
@@RaceProvenMotorsports Thank you!

How much is the build on the ZR1? Gotta be 50k plus right?
Around there depending on options yeah

E85 doesn’t do much on NA vehicles
2009 ZR1 does it need heads done because of the valve issues on the Z06
Yes
@@RaceProvenMotorsports ok thanks
... that Maple Syrup power.
The ending of this was weird almost seemed like a bbc show ending like is it over ?
Camera man wants to fight ok lol lol
Watch out Matt is a one punch knock out
Fran do you remote tune also ?
Yes. Email me
Matt🤣
I called up there to get a quote on truck project guy told me y’all wrk on cars 16’ and newer so why I see shop full of c6s I feel it’s a bunch of bullshitt honestly

We have worked on 2006 and newer vehicles for for the last 10 years.
I’m the first view and like
We are all very proud of you lol
Yes, very proud
keep up the good work...
dont see the stage 4 or 5 performance packages for c6 zr1 via website
Just email or call us.
