SL65 Black Series Turbos Pictures
I have received a lot of PM's with respect to the Specs of the wheels etc. We did not measure the wheel unfortunately but we could confirm they flow much more than the average 65 turbo without a doubt. The person doing the job said they extracted 850rwhp previously. The Port job also increases flow and ceramic coating increases efficiency by decreasing the heat tremendously. Lots of people on the fence and some just trying to get money straight. Thanks for the interest!
Also trying to sell the turbos as a kit along with Ceramic rotors and Drive shaft, last alternative will sell alone if needed.




My tuned CL65 hit 700rwhp ages ago when I ran 10.72@129. and this was sucking hot air under the hood. Another 100rwhp with better tuning and better air movement is not out of the question, specially with a larger diameter turbo like these.
Information comes from the person who put a 4800 lb CL65 car in the low 10's and almost trapping 140. Definitely a credible source in my book.




I'm thinking stock vs stock these are probably worth, at best, 50 to 70 RWHP over what you would get from the factory SL65 turbos. I would still love to see an 850 RWHP dyno on a SL65. I've been hunting for unicorns for a while and have yet to see a legit SL65 dyno that high.

The SL65 has nothing unreal compared to our 65's. Only difference is intake and Turbos. No one has taken one to the extreme that we know of.

Even if Renntech put a lot into tuning, why wouldn't they offer that package to others after investing all that time? Nothing even close has ever surfaced. Over 10 yrs of 65 motors being made and there are much deeper pockets out there than ours. As you know alot of effort went into weight reduction and rotational mass, (CF drive shaft & rotors), along with what ever was stripped from the interior. That will help with the 1/4 but not with power. I think I'm on the same page with BlownV8; without knowing what else is needed to get that power or see those times and speeds, its a hard sell. Who knows what is missing for renntech to replicate the setup and at what cost? Would it be as simple as just getting a renntech tune after installing all the parts? If that's the case, I'm sure you will find people to be alot less apprehensive about making the purchase.
Good luck with the sale, and too bad responsibilities prevent you of moving forward with the project. In the end its not about numbers and dynos, but true performance. I hope they move into the right hands to repeat what was done for SGC's CL, maybe some of the little guys will eventually get a chance to share some of the trade secrets.
SGCs tune was not one right off the shelve. Hours a hours went into tuning it. Numbers speak for themselves.
Again everyone is entitled to their own opinion, obviously everyone is expressing theirs but until I see a slip nearly trapping what SGC trapped I'll continue with my opinion. If these don't sell I will store them and save them for when I have the time to put them to the test.

It would suck for someone to buy them and not be able to tune the car to the parts true potential if more is needed to assist the turbos besides the tune. Hopefully, when the time comes what ever is necessary to get the greatest power is available to the owner and tuner. A ton of tuning R&D still comes up with a recipe that can and should be reused with much less effort. Its too bad more about SGCs car didn't surface over time. I'm sure many would love to know whats needed for a high 130 trap. I know he was sour with all the nitrous accusations so now that info remains with only a few.
I think it was amazing what you did with the EV-12 and the monster turbos with custom manifolds, despite so many set backs. Your 780 # was super strong, but this upgraded turbo seems to be able to give you better number down low as well. Its too bad there aren't more upgraded turbo and ported log manifold cars out there. If they can make that much more power, it would make the V12 platform that much more interesting to follow.
The beauty of it is the guy who helped in putting together SGCs car has also given me the aid of sorting my car as well. Yes turbos alone didn't get him there, it was the package of light weight stuff along with the power delivery. It's why I don't want to sell turbos alone. I keep the package together or none go at all. I definitely believe the combo should get someone in the low 10s and maybe colder air in the high 9s.

More performance is realized thru an optimized version of the ole' 5 speed Slush'A-Matic

Also keep In mind the assumption of having all the other modifications mentioned above are assumed in order to obtain 800whp, obviously just these turbos alone will not net you 200whp. They will compliment everything else. Just like adding turbos alone will not get you into the 9s. Hope that clears up the confusion.

Keep in mind no one has taken a Black Series to it's extreme. Who ever buys these cars want to keep it as a daily driver and are not looking to take the thing to the track. Wealthy individuals are not into the 1/4 scene as much as we are therefore you will not see true potential with the exception of 1 here and there.
This particular dyno from a black series had Downpipes, Ram intake and Tune. Not sure what octane but you get the picture. Look at that torque curve...

Quite sure if they added a rear reservoir to this thing another 35-40rwhp is obtainable.




I feel it is a diservice to someone buying these that you are advertising as 850 RWHP turbos. It's like selling a.Chevy 350 engine as 2000 RWHP capable with minor mods. Sure, someone could probably get that much power but it wouldn't be from the way the engine stood when sold. You are talking major mods none of which no one n this discussion knows how to do.

Yet I just inched and showed you a 700+rwhp with just a few mods...
Hey man, take it as you wish just please do not discredit my thread with your guess here and there information. If you have facts then post them. Prove me wrong, I'll wait. Please do not assume, speculate etc. And for the record this is defintiely bolt ons, not sure what part is the major mods here other than Black Series turbos. If you call swapping injectors a major mod than I'm definitely preaching to the wrong crowd.
Now I know why SGC kept this **** in the dark for years.

Don't blame the man one bit.

I'm not the one here with anything to prove. I'm not trying to sell hopes and dreams with no formula to get there. It's you who need to prove me wrong. You have posted nothing that proves these are capable of taking an SL65 to 850 RWHP.

Hopes and dreams? that's on your side of town, nothing but facts from people that have first hand experience with these caliber of turbos. You'd be lucky if you see these in real life.
I just noticed something, have you ever even had a CL65?? Ughh Lots of experience with this platform, Jesus. How could I not see that one coming.
I apologize man, I am the stupid one here, can't believe I am arguing with a person that has not even had or tracked this platform. End of discussion.

I would never sell a performance mod or sell a car advertised as x hp without something to back that up. It would not be "I know.of a.guy who ran a great trap." Are your sure these were on SGC's car when it ran that trap? I know more on the topic than I'm letting on.

NOW please step away from my thread, politely. End of topic.
Perhaps you would have an easier time selling these if you installed these and put up a Dyno or even better a time slip?
Not trying to start a bashing contest here, but BS is BS and that turbine housing will not support 850whp. Unless you are basing this on the bogus claims of MKB and their 1000hp SL65bs. You know the one that ran a best of 11.2 at around 128 or something around there.
The BS-Turbos have good potential and are a TRUE upgrade for the stock turbos.
Personally I would have gone a little other route with the BS-Housings. According to my tuner the housings realistically are maxed out quite a lot before 850 whp - 950 Crank HP.
But nevertheless you can gain a lot in comparison to the stock turbos.
Good luck with sale!

Understand and point well taken. I honestly do not have the time to play around with the car and the time these mods require, I embarked in a very competitive MBA which requires a lot of time and sacrifice, plus the money I am putting into it. Can't sacrifice juggle anything else right now. If they don't sell I will hold all the mods until I do have the time.
Correct SGC did not have these turbos when he ran 10.2 and yes he had roughly about 720-740 rwhp on his stock 65 turbos. On BS 65 turbos another 80 rwhp in combination to a few other things done are definitely doable.
