To make right at 900whp you should only need 23psi of boost on a 10:1 compression engine. It is more critical that you have your turbo/turbo kit efficient. The higher the whp the easier it is to hurt an engine because your efficiency is not there. Cool dense air makes power. When our cars are right they just make power easy. There is no tuning trickery

. That being said, your turbo points are 100% correct. Drag world has been in front of that for a while. Infact, the sensor setup you have is very similar to what I see in top tier drag builds.

I am going to use 10:1 compression ratio. Your numbers will go up or down depending on the compression ratio you have. 9:1= lower whp at 17psi of boost. 11:1 = higher whp at 17psi of boost.

If you are not hitting somewhere close to these numbers you have an issue that needs to be addressed. So, stop turning up the boost to try and make it hit the whp numbers you want or you may hurt your engine.

17psi of boost, 10:1 compression ratio on pump E85
720whp

17psi of boost, 10:1 compression ratio on Ignite Red with 1/2 deg more timing.
770whp

An additional point is that boost PSI is a measure of resistance. 17psi on one car is different on another car depending on restrictions.

BTW, this isn't so much for you Spooler. Just an addendum to your thought.

A good tuner will show you where the engine falls off and explain why instead of forcing it.

I am afraid we don't have any of those on our platform. The person who tuned my car is not from the VQ community. Best kept secret there is.

FIFY

Sorry bro, its the truth for this platform

Glad it's all come together and its all working for you. You've earned your results 10x over.

You have no idea. LOL This last upgrade was not cheap. Custom work costs. It is right this time. The car is amazing. We all wish we had the cookie cutter upgrades to make the power like other models and be reliable. Do this to get that whp type deal. Nobody makes a turbo kit that can make 1000whp without some serious modifications. Some kits you just sell and start over. I am happy with my car. At the end of the day that is all that matters.

Life has me busy right now. I will get to tuning my car in one day. It will just have to wait. I have other more important things to deal with right now.

That's right. If you use a quality MLS and head studs with the CSS it should hold at that level as long as your turbo and turbo kit are designed correctly. If you want more you have to do something to create more sealing pressure.

Examples:
Darton sleeves with step deck cut block, Quality MLS, Head studs
CSS with a copper o-ring/Quality MLS with headstuds.
CSS with Top fuel hoops, copper headgasket, Head studs.

Every one of these solutions can be broken if you don't do not size your turbos properly and do not have an optimal turbo kit. High drive pressure will take out a headgasket with the quickness. Too high of cylinder pressure to low in the rpm range will make our blocks dance. We are not able to push our blocks like other platforms can. At 800whp or above one little tuning mistake or pushing your small turbos too hard will cause major grief. You have to know when to stop turning up the boost. You will get warning signs before destruction happens. A standalone with sensors is worth it and will pay for itself. One rebuild will cost more than the cost of a standalone.
