I&#39;m going to have some pulley&#39;s custom made for the whipple, and was just wondering if there would be any interest from the whipple guys on here. These will be 6 rib, ultra-grip pulleys from Reichard Racing. If you are interested, let me know, and we&#39;ll get the order started. The smallest that whipple makes is a 3.5" I plan on getting a 3" pulley, but I might be open to a couple other sizes. Who said boost is addictive?

I am interested but will smaller pulleys fit and what boost ranges are the. I have the stock whipple 3.75 at 5lbs 7 if It is cold outside. I still have the whipple electronics hooked up. I do not plan on keeping them though. I have 42lb injecters but I think I need a fuel pump upgrade before I put them on. I have got to finish hooking up the meth. All I lack is running the ground and power wires and filling the little tank.
I think I need to pin the crank before I get to carried away.

I wouldn&#39;t be getting them made if they didn&#39;t fit. This might be a little more than you&#39;re interested in. The stock pulley is bigger than 3.75" I think its 4-1/8" The 3.5" whipple pulley should make 12 psi. I only saw 10, but I had a non blower friendly cam that bled some off.

The stock pump is more than enough for the 42# injectors. I ran my 44# injectors at 120% IDC and the pump kept up just fine.

I&#39;m considering a 3" pulley which would probably make around 16 psi on your setup. I wouldn&#39;t recommend doing this on a stock long block. I added some cubes and need to pulley down to compensate for it.

I didn&#39;t mean to sound like a dumb ass. I just did not know if you had an extended snout with a different pulley setup. I just looked at mine and it is a 4.5" Are you going to sell any of your other pulleys if you have any. I would be interest in any you have. I at the moment do not want to blow my engine and 8lbs is about the most I would try for. But if the price were right I would buy the pulleys just to hold on to them for later.
Thanks for the fuel pump info I will be putting those injecters on soon.
I hope your boost quest goes well.
I would love to know what a whipple and a stroker will do.
thanks

The pump will keep up better... It will have a bigger injector(nozzle) but it will cut the injector duty cycle down 30+ percent ... I installed my Hotwire kit and the 225 pump.. the fuel pressure still dropped &#33;&#33;&#33; just like it did before I spent 300.00 and had the tank out 4 times &#33;&#33;&#33;&#33;&#33; I kept thinking the problem was in the bucket or sump or something was wrong... I gave up and put a scanner on my truck .. 120 percent duty cycle and 25ms the reason why my fuel pressure was dropping was i had 10 wide open injectors ( 2 boost injectors) it was like having a wide open hose that could not keep up... bigger injectors will fix everything .. By making the IDC alot lower it helps the pump keep up and constant 58+psi ... Dont let the stock pump hold you back &#33; KC
