How much power can the 2.0 block take...
I was toying with the idea, but i figure it wasn't appropriate for a street car (i thought there might be cooling issues). There are a few guys that run filled blocks on the street.....haven’t heard to many issues.....
BOOM!!! Souvineers for everyone!!!
Saw a 2.5 pontiac block with a hole the size of your head out the side. It was a partially filled block for the busch series nascar. I got his backup hatchet head crank. Its been sitting in my garage for years waiting for an S10.
I can see filling a block for a drag car that takes a couple seconds down the track but I cringe when I see a drag evo. Its such a waste of a platform this is a rally car, it does well on a road course but why would anyone build a drag car with an awd car. you could make all the hp in the world with a 2JZ or LsX and put the power down.
in the case of shops using a drag series as a proving ground for parts, I disagree, any motor with enough boost or juice can go down the track and need a rebuild. The real test is evo's like the sierasiera that was melting exducer housing and hellped in the develpment of the borg warner EFR series. That is a product being performance tested and when proven reliable on a roadcourse then it is reliable on the street but only because a half bolted car makes a 9 second pass just does not impress me.... especially if the block is filled
now back on topic....
filling a block is a way that "people" build dyno queens so that fanboys can swing on their nuts. Mad respect to shops such as AWD motorsports that are making the hp with out filling their blocks

They make a special block filler but yeah its just like concrete or a stiff grout. V8 guys been doing it forever. It stiffens up the cylinder walls so they don't distort and alot of drag cars that are still using a stock style block may be completely filled but your talking about a short couple seconds of run time then shut down.
LOL my car is no dyno queen, it's ripping it up every single weekend, but when I make more power I want it to be safe, thats why I'm looking into this half filling business because this car is a street car first and foremost.... still got a/c, etc.
Just looking forward to n2oiroc's reply...

The motor is built but not swapped in the car yet. Buschurs old motor was filled and he drove it on the street with no problems, quite a few others have done it also. Mike reichen helped me with the motor build and he also said there are no issues driving it on the street and i made it clear thst it will see a ton of street miles and hours strait on the freeway. I did add a 5.5" spal fan to the oil cooler though as the oil temps might be a little higher.
My block is filled also. 2.0 aluminum rod. I drive It in 98 degree weather at times with my FF kit and mini radiator with no issues at all. So far I've done it for a year with tons of street and track abuse.

apperently you dont realize how many people hard block their cars. it has nothing to do with dyno's or fan boys. its simply something you do to make the a high horsepower block more reliable
Wow good to hear! Thanks for the input everyone, this is making the decision a little easier for me. Here in OKC it would see over 100+ in the summer with a/c. I'm thinking if I half fill it, nice full sized radiator, some water wetter, should be good to go. Also like the idea of tossing a fan on the oil cooler!

im using this to trigger it, i had a bung welded in my oil pan.

I run my car on the street all the time with no issues. Its filled 100% and uses our standard oil cooler setup. I have taken it out for 45 minute plus drives in stop and go traffic several times with the oil temps only getting to about 170. Once its moving they stay around 115-130. I am not sure what kind of power it currently makes but I know its a lot.
