Low boost 24v

[Lnixon97]

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

[Lnixon97]

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

[Me78569]

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 

[Me78569]

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

[Me78569]

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

[Lnixon97]

Even though they’re only 7x.09 vco?

[Me78569]

150's are normally 7 x .010's

 

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

[Lnixon97]

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

[Me78569]

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.
