Why a walbro 255, why not 190?

[Ttop34]

I was talking to a guy at a speed shop today and he told me that the 190 would support up to 400hp and a 255 over 500hp. He also said that a 255 works harder so a 190 would stay cooler and last longer. Is there any reason to go with the 255 rather than the 190? I'm thinking very hard about a 100 wet shot but still with that and the cam I shouldn't be up near 400hp right?

I know some of you have the walbro 255, I just want to know why and why not the 190.

the only reason i got the 255 was because i live by the modo go big or go home(if you can afford it)!!!!

Well I would like to do the same but if it's pointless over kill then maybe not. I was told the 255 works harder and builds up more heat. I would think that extra heat might even hurt performance. If the 190 is going to be more than I'll ever need, shouldn't I go with that one?

The reason im going with the walbro 255 high pressure pump is because i am going with a supercharger cam and spray

because a 255 is cheap enough that it doesnt matter. It might be overkill but why risk it. Because I plan to have 500 HP in the near future.

Now why would anyone want to run 2 power adders? lol

I have a walbro 255 on the shelf waiting installbut The inline blower pump is doing the job fine for now.

I have the same opinion, for the price you might as well go with the 255. Always plan ahead, you never know when you might decide to put some monster big block in there. ;)
