I dont think cooling is an issue overall but there has to be som argument that taking up that much of the top of the cylinders without direct cooling to the hottest part of the sleeve has to cause some sort of issue. i would imagine on pump gas the envelope couldnt be pushed as much do to an increase in the potential for detonation with hot spots. But overall the system seems to work very well for the cost and thumbs up to these guys !

 

It's only half an inch or so in height and it's aluminum. The aluminum is going to dissipate the heat. It still flows water, may be slightly restricted, but the OEM water pump doesn't flow that much for any noticable difference.

I personally don't see it being an issue. Look at the other sleeving companies that do something similar IE: ERL and Darton (mids)

 

Aluminum dissipates heat around 6x faster than iron, so a stock sleeve .090 with the rest alum will dissipate heat from the top of the cylinder FAR BETTER than any ductile iron sleeve which is around .270 Benson all the way to closed deck blocks like MID's/AEBS.

 

I am not saying it wont dissipate heat well BUT honda designed these blocks with open deck for a reason is all im getting at. It keeps coolant at the top of the cylinder which transfers heat alot better than a solid piece of aluminum at the top. I am in no way saying it will cause a problem as your system really seems to do a great job just throwing it out there. I have a spare GSR block laying around that i might even send out just to try these out for my new setup next year.

 

Im gunna get this done to my block and have fun 600HP street car...

 

I just may have a block for you

 

Nice. Good work Jeff

 

Update to YoSolo's earlier post.

Turbo was replaced and here are the results. Same HP 8psi less boost. HondaDay here we come!! Great job guys.

 

We just went 10.6 on a 60-1 today in jersey CSS is holding up just fine.

 

Consistent 10.5 @ 140mph runs this weekend on the CSS block holding up great...

 

700+ whp on oem sleeves! Any b20b/z blocks with this process making 500+whp? I have a b20b block that I want to throw some crower I beam rods and some supertech pistons I have laying around and have a fun street car with 400-500whp on a 2.0L with out sleevinf it. Pm me a price.
Thanks

 

I do not see this being a problem at all.

 

Sounds good.
But i still want to know if there have been b20b/z blocks that have gotten this process and what power levels they have been pushed to out of curiosity.

 

At this time I have not had any B20 people report back with dyno sheets or timeslips. Most of the B20's I've done so far have been for all-motor set-ups and NOS.

 

Lets do this!

 

Mid 10's all weekend. Broke the trans in eliminations.
Best ET 10.48.

Red hatch near lane.

Hopefully by the time I am ready to ship mines out. Someone will have Dyno sheets posted.

x2 i am also interested in seeing some dyno sheets.

 

I'm in this for sure! what's the turn around time?

 

Guys, don't let this become a for sale thread, or anything that even resembles a for sale thread.

 

Just got my Ls block back from Jeff, the turn around was awesome and really fast and was also great keeping me updated on the block, he received the block last week and I just got my block in today and Im located in south TX, Ill be getn the block back together and try and get some #'s from the dyno etc. as soon as im able to, Thanks again!

 

Any new numbers or setups testing these blocks to there potential? Just curious and trying to get excited about this and get a block sent to these guys.

 

we have one at my shop that is being finished up for a customer. B series 6262 pumpgas car. I will have dyno results as soon as we get it broke in and tuned

 

Boost and potential power goal? Really enjoying this thread, can't believe it's not gaining more attention, I gotta quit talking about it and just get a 2.0L block and see how well itll withstand the nitrous I wanna throw at it.
