Yes she gave up around 30 psi on my 62mm, probably around 7ish.

fuel psi was about 80 and would fall bad into the 60s by 8000 rpm to redline, I'm on 2200s as well. Id say anything over 6-650 is unsafe on a single 450.

 

Update:

Getting my 8.8 rear built. I sold my Puddy mod before I blow it up, and knowing im gonna wanna do some track and launching, I went ahead and got the 8.8 kit, with 1500hp axles.

Just waiting on Rear end to get built and than install the kit, also ordering some welds

 

 

Jasons kit, and just a tru lock, nothing fancy.

 

Welds RTS are in!!! and some STREET Rs Cant get any photos till I get back home... But ill post them in a few months Im pretty excited.

 

WOW those Welds do look awesome I just searched them on google.

Is it possible to run any street looking tyre on these? Something that will not get to much attention from police?

 

STreet Rs are DOT they are a drag radial.

 

just now seeing this , your basically copying everything i did, but the proper way from the beginning.. just need to build that block sooner than later

 

I also do it all my self in my own garage so takes a little longer, on top of customer cars too.

Where i'm going, i don't think i need a built block lol they don't even want these problems with a stock block lol

 

Not sure if you saw this
equal cars, equal PEAK HP, camera car is stock motor with 730 peak, opposite lane is me with 730 + better power curve ( built). i let out as soon as tires spun and started to change lanes uncontrolled
I had a dynograph overlay somewhere.
