I have a 99 24 valve and I took it to outlaw diesel in Indy because I wasn’t seeing the boost results I wanted they fixed a boost leak and a fuel line like but said I don’t have enough rpm to spool to the boost I want I have an aura 5000 turbo 150 injectors 4K Hamilton springs arp head studs south bend dual disc quad adrenaline banks intake and I’m sure a few more performance parts I’m forgetting but it’s only hitting 23 psi with the tuner all the way up does anyone know what’s up before I take it somewhere else

The Aurora 5000 is a huge turbo for a 2nd gen vp truck.   It is going to take a ton of rpms to get that thing going.  It is almost considered a secondary turbo in a compound setup for a towing application.  

 

What A/R housing is on it?   T3 or T4 foot on it?

 

 

Honestly you need some REALLY big sticks if you want to have any hope of lighting that thing.  I would fix any boost leaks, add 6 x .013 injectors and hope it lights by 2500 rpm.

It’s the t3

What a/r housing?

 

Honestly that turbo is a terrible turbo for a street application vp44

I think it’s the 1.0 housing I’m not positive though 2029502218 is the part number

What are your goals for this truck?

 

That turbo wont make boost with your injectors.  You need more fuel and more rpms to get that thing to light.

 

I would recommend ditching the turbo and going with a 62 sxe or similar sized setup from @dieselautopower depending on your goals.

 

If you want to keep that turbo i would suggest at least 6 x .013 injectors.

I’m wanting to get 650 hp I think I’m going to get a set of industrial injection 6x.016 and I have a brand new air dog 200 4g sitting around I need to install 

Talk to weston at infinite performance.  Way better injector for the money.

 

You will still only have a truck that makes power above 2500 rpm.  You wont be able to tow and i wouldnt want to dd it.

 

If the truck has dd duty and you want over 550 hp i would recommend twins.  

 

Vp trucks just dont do big singles well.  

 

I still dont think that turbo is right at all. It flows way more than you need.   Why try and under use a turbo?  Takes forever to get into a useable part of the map and you waste the top end of the map.

 

Its just the wrong turbo for a vp

Sorry I forgot to mention I have a 60mm borg just siting around that I will put on after the injectors for a compound setup

Thats a much better idea.  Honestly you might be happy with your current injectors if you throw the 60 on there.

 

That will be 550 hp worth of good usable fuel

Even though they’re only 7x.09 vco?

150's are normally 7 x .010's

 

7. X .009's are a good fit for a stock turbo.

Roger that I’ll slap the 60mm on and see what it does thanks for the help man

Yea.  It will run much better.

60/s475 should be good for 600-700HP.

 

You should be fine with a set of 7x.014 sac for about $600.  

 

S475 and compound piping is under $2000 for the set.
