UPP turbo kits are available from many UPP supporting vendors.

When it was first proposed to build turbo kits, I warned my friend CK that corvette owners are tough critics on parts for a corvette. The original kits tried to just make the least expensive kit that would last as long as any corvette owner would own a car with lifetime warranties on pipes and turbos. Still there would have to be an evolution because corvette owners wanted 304 stainless, ball bearing turbos, and name brand parts. Now kits are available with all of the above for the guy looking for a better product and not just entry level.

The kits have grown up so much since the original kits adding a degree of quality that some may not be aware of. Other markets have taken off such as the camaro kits which use fully custom in house turbo manifolds, top mounting turbos in many apps, and pipes that have jewelry for welds with accurately cut pipes from the addition of new tooling and an artist named Brett overseeing the welding dept.

Here are some pics to show the new UPP:

Is that an LS powered boat he is tuning?

nice quality affordable stuff, i cant believe there are not more UPP powered vettes on here, i do not own any upp products but my next project will prob be one of the turbo kits they offer,

GTO and Camaro kits are really common. The last Camaro built in the shop made 650rw on 7psi with over 650Tq.

What about a C6Z kit?

SpinMonster

I know CK said they were looking for a C6Z owner to have the car used to measure for the turbo placement. The variable on the Z and Grand Sport is the dry sump res. CK has already changed the format on the Camaro to an in house turbo manifold that is far better flowing than log style cast manifolds because of curved rather than sharp angles inside it. The use of such manifolds can be used for Z to locate the turbos outside the fender locations.

The canister can also be relocated.

The camaro's turbo manifolds made in house are like shorty headers. I'd push to get that format for the Z.




Inside one of the turbo manifolds collector for a V-6cyl. Very accurate cuts. As with everything, practice makes perfect.



Its just an issue of measuring for fit on the Z. The first car gets it fully tuned/installed for less than the kit price once its done. The camaros that get the top mount turbos with the turbo manifolds are seeing 650rwhp at 7psi and peak TQ is in the 4000-4200rpm range over 650rwtq.

I'd be interested in the details of the finished product. Let us know what you find out.

SpinMonster

In the case of the camaro, the stock exhaust manifolds flipped upside down simply don't fit the turbos in a top mount configuration. They dictate where the turbo sits. Custom manifolds put the turbos where they needed to be. When they saw the result, it became a possibility that all the kits would benefit from it. As it sits, custom manifolds are not included in the corvette kit. I was thinking that based on the camaro kit's results I would like to see it happen.

As for what max power you can make on stock manifolds, instead of 1100-1200 it may have made 1300 with the same boost for all anyone knows. When CK switched to the top mount design with custom manifolds, it eliminated the oil return pump and made 8% more power on the same boost with less heat. It added reliability.

I'll take a cast manifold over a welded one any day if it is a street car.

SpinMonster

Me too if its a cast turbo manifold designed for the application and not a GM exhaust manifold.

They definitely offer what seems like a good system. I was surprised when they offered a kit for the GTO so late and give them props for it. Could use a lot more shops like them out there.

Looks really good, any 1/4 mile records?

Cordes Performance Racing

Your right because the factory manifolds don't support almost 1200 rwhp.

SpinMonster

Our tracks have an average DA near 9000 feet. Unless those near sea level buying the kit have times to post, what we have here is irrelevant. The correction factor at my elevation is 28% so 1000rwhp here is like 720rwhp at sea level. Your car here would barely beak into the 11's as your 470rw here is about 340rwhp corrected.

No one brings their car to Colorado for bragging rights.

I disagree Guy, If I lived out there I would gladly show you, I would still run a 10.60, I have 492 rwhp, but that doesn't mean a thing, if I ran at bandimere speedway yesterday it was in the 5000 + DA I would have ran 10.6s and 9s if sprayed 100 shot guaranteed

SpinMonster

I knew you were going to say that.

dennis50nj

I only said that after checking the DA at all 5 Colorado tracks for yesterday the highest being 5814 elevation and the lowest 3468 elevation, with varying BP and Temps +5500 DA to +1766 DA, I'm sure I could track DA search and get a great day and get close to a negative DA if I lived out there and still run a low 10 in Colorado

SpinMonster

Negative DA lol. You are seeing the best of days right now off season.

I've always liked this kit and the ones I've seen from UPP for other platforms. I still want to see someone do a built motor build with the bigger turbos.

SpinMonster

Hey Bill, long time.

There have been a few forged motor builds. I know because I helped assemble bottom ends with CK. I haven't asked about max effort results yet. We usually talk about everything but cars when I'm there. I know they went over 800rwhp but the limits they see are that no one wants to grenade the drive line. We unfortunately have to tune at our elevation so the end user at sea level has to retune at some point on higher boost. CK tends to release the cars under 800. The vast majority of UPP cars get shipped in for builds.

dennis50nj

there is always a good day when you know what and where to look for, also I have found a 3% rwhp difference for every 1000 ft DA change, I'M sure I could check those tracks via drag times and find a dozen DA days to make a 10 second pass NA:ro I might not find a -DA but if we fell somewhere in the middle between your 9000 ft and my 0 ft I could still make a 10 s pass NA:flag
