Edit: Numbers in

Car got dynoed today. Head and exhaust manifold are holding it back for sure, but Im still happy. Car is a beast
Dynojet numbers

15lbs - 368hp/268trq
20lbs - 435hp/311trq
30lbs - 513hp/366trq



So I've been talking to Mac (TheShodan) for quite some time in selecting a turbo for my LS projects. Well it finally came down to the time the past couple months. I decided I would send my poorly working SC61 to him to be rebuilt and upgraded.

What he advertises for the 500-600whp range guys is the STC reaper. The 62mm Billet wheel is custom designed by himself and another engineer specifically for better flowing heads, like hondas. It supports more power at lower pressure ratios due to the splitter design and angle of the blades; as opposed to a 6262 which has been making big power for evo guys higher up in the range. (This is what I've read/been told, Im sure he'll chime in).



2 Days after he started working on it, I came home to an unexpected box at my front door. Made my weekend...

Here are some pics:









Im not representing the company or anything, but small business's that do quality work should be mentioned.

I havent started tuning the new turbo yet, but it will probably happen this weekend. The old SC61 made 500whp at 27psi and 430 at 20psi. Im looking forward to seeing those numbers with less boost. Car will be on the dyno April 2nd so this series of turbo will have one of its first graphs on a Bseries setup posted here.

Anyone else with this turbo should post up results/pics/numbers.

 

Good to hear you're trying it on a B series. Sounds like an awesome unit! Why not put in on the dyno March 2nd rather than April 2nd?

 

Dyno day. I street tune my cars

 

Nice ! !

I'm currently waiting for one of his "Silver Surfer's". I can't wait to get this thing on the road

 

good stuff chris, ill be sure to post my results as well.

the only thing stopping me besides school and work, is all the snow that my car is behind. I think theres a pile of snow probably 4 feet blocking the garage door my car is in LOL

 

Nice

 

Talk about high flow heads and what not, then have that manifold? Come on now.

 

Made 500whp on pump gas. Not really a whole lot more to ask for lol. Kinda proves you dont need that topmount bandwagon to make power. The head is stock other then cams and retainers/springs.

Could probably do a little better with something like a ramhorn, but then Id have to change the downpipe and chargepiping and all that ****. Not worth it.

 

I was talking more of the collector and runner length. You can make 500whp on a log. Does not mean it is the best. Not to **** on your thread, but it is just silly to build a turbo for "high flowing hondas" and have a bottle neck on it.

 

I agree with you, some headwork and a real manifold will free up a good amount of power but No one said this was best. It meets my goals fine. I bought it with that manifold. If I stumble across a grand I'll upgrade it

And that was speaking in generalities. As in hondas in general have really good heads stock.

 

im only assuming from your sig... but u made 430 at 20psi and 500 at 27psi... 10 psi per pound means a huge restriction up top... i think upgrading that manifold probably would have been more beneficial than the turbo...

27psi on pump gas is a recipe for disaster as well... if you dont have money for a ramhorn or something along those lines you definitely dont have funding for a blown motor... and put that thing on the dyno to get timing correct... that catch can setup saved your motor

regardless... sexy turbo!

 

So my motors gonna blow up because I dont have a ramhorn? Good advice. The turbo was blown, and it needed replacement anyway.

You can tune timing on the street. Its called reading plugs. I didnt tune the car when it made 500whp. It was my buddies car and he has been tuning cars for along time.

How did the catch can save my motor?

 

no were in my post did I even make a possible reference to blowing your motor because of your turbo manifold... i clearly was stating that your manifold was a restriction... that was an irrational response and in no way related to the point i was trying to make...

You never stated reasoning for getting a new turbo... which now you have justified...

whats the purpose of a catch can? either you bought it because you know what it does or you saw someone else with it and wanted one... again your being irrational... 27 psi with pump gas is dangerous...

the street vs dyno tuning topic has been covered numerous times in this forum... i do not need to justify my comment about dyno tuning because its proven by numerous tuners on this forum...

 

Always a pleasure to see his work in action, I have a few guys including my best friend / business partner who will run one of his turbos here in the future on our shop car.

 

Yeah it was JDM yo so I got a catch can . The car has been on a dyno, and the timing wasn't touched as far as I remember from the street tune because it was already very close. It picked up a little power adding timing (10whp) but was then backed off for safety.

Prove to me 27psi is dangerous when you really have no clue how the car is set up. I'll take my chances.
If anything this turbo will be "safer" as it will be more efficient, and will require less boost to hit the same numbers.

 

Did some tuning this past week. Turbo spools roughly the same if not a tad faster then the cast wheel before it (About 20psi by 5500) Just remember this is a nonvtec car with an aggressive cam that doesnt really come alive until that rpm anyway. A vtec head/cam would spool faster no doubt. Transient response is noticeably better, especially in between shifts. Old duty cycles for the boost controller needed to be bumped a bit in order to reach old targets (meaning better flow?).

 

Good stuff! looks like a nice turbo for sure..


I know my 6262 was a tad bit faster in spool than my friends SC61, both setups very close..

 

cant wait to see the numbers

 

you got anymore info on the wheel? And TheShodan's compnay?

 

Yea id like some info the company. I like reading his posts on here, you can tell he is packed with knowledge regarding Turbos. Id be interested in seeing some numbers. I moved up from a PTE SC61 to a PTE 6262.

 

humm. This is the same turbo that was posted on a local forum. Thanks for taking a picture with the comp housing off. I was told they cannot post pictures of the wheels, at least publicly anyways. Any more angles of the wheel?

 

Thats not one of my pictures. I took that from a thread Mac (TheShodan) made.

 

very nice...

 

lol you're in the same boat as me. I agree with you. I make 490 on a rev hard log mani. I don't see the need to pay $1100+ for a new manifold, dump tube and DP. Plus, like you I'd prob need to upgrade to a 44 wasegate.

 

cant wait to put my STC turbo to use. Just got it a nice blanket because MN winters are cold!
