vortech/stock block let go...so *knock on wood, reliable build thread ;-)

Yea it actually picked up a good bit of boost. Was seeing 21-22 w crappy filter now seeing 24-25psi. Which is great for power but it made me max out my pump. went to 1200cc injectors and a walbro 450. Still maxing out my pump so installed a Kenne bell Boost-a-pump for now. Eventually will go to a twin pump setup but the boost a pump is working very well. Finishing up the tune and she will see a dyno again. Should make a decent power jump, she made 608whp at 18 psi with a 8.8:1 motor. Now it's at 10.0:1 compression and 24psi so we will see. But she runs super strong

W a digital thermo under hood temps were almost a full 30 degrees cooler after a short drive with the vents then they were without them. What I was most impressed with was the fact the coolant temps on my gauge stayed at 180 degrees through wot pulls in this Texas high 90 degree weather
Same hood vents a lot of the Pirelli world challenge cars run

Update, it's been a year since the IPP motor let go at last years 1/2 mile event... the garage rebuild and car has been great still. A lot more racing and she's doing great. We even managed a 160MPH pass in the standing half mile event this weekend!

It "let go" when you had a blower belt come off doing over 140 mph at a 1/2 mile event. Not because of a faulty motor.
If you have ever watched top fuel cars loose a belt; it is not pretty what happens to the motor. You are basically flooded with fuel and no forced induction/air to burn it off. Any motor would self destruct in that situation.
Just wanted to be clear on that.

Just to be fair for people that don't read your whole thread, your motor that we built ran flawlessly for over 2 years and many track events.

Well it's been a good 2 years of road racing the car and beating on her pretty hard. She appears to have gotten some engine damage at this 1/2 mile event. Car ran a 149 with my 7200rpm map (have another map set to 7600rpm) so she may have had some more in her. But threw a belt at about 140mph at the end of 4th gear and threw oil out the valve covers when it happen. Pulled back into the pits, threw a new belt on and she was knocking pretty good. She never lost oil pressure as far as I know and still has good pressure at idle. Never got hot either. Will be breaking into her some soon. Not sure what direction I will go from here. May rebuild and keep pressing. Or make the swap to the LS world for the convenience of parts availability and reliability. Or may sell everything and start a LS 240sx build for road racing. We will see.
