How many pounds of boost?

I don't know anything about the guy on Facebook's build but in general you don't hear about about many builds that are 900 plus because they seem to run into trouble at about 20 psi according to Seb. He has gotten close to 1000whp a couple of times on his Z. The first time he lifted the head pretty badly and the last time it was nothing "to bad" but he could see a few drop of antifreeze and it has held up fine since pushed it. He says the car if basically not driveable at full boost. He said that he broke the tires loose in 5th and 6th gear. He says 5th gear spools up as fast as my 3rd gear does at 600whp lol. I told him I don't want more than 17 psi lol.

Yeap, 18psi is the max I want to run. If I can hit 680-700hp on MA's dyno at 17psi. That will be good enough too. That would be 800hp on a dynojet.

The build in question is a closed deck IPP stage 4. Aside from the closed deck and moly coated race bearings it's the same as my Stage 2 , but I paid for upgrades. The shining star of the build is the headwork and C2 cams. Also this was on Ethanol.
Also Seb I chatted up Seb and he believes that 16+ is where head lift becomes an issue, I'm gonna have a bit of faith in the L19 kit and I told him I'd like to take it to 18psi but at his discretion. So now I have to send him video of my wideband during my next pull and from there we go to map 4 and possibly 18psi. And Matt said he believes they had it at 29psi in a post.

There is a point you reach with how much power a car can handle. Once you go beyond that point. The car is no longer fun to drive, but a handful and you're fighting it.

Yeap, that is right at 700-750hp best I can figure. So I built for 800hp, that doesn't mean I have to run it at that.

Seb is building my motor and I told him for my purpose I really don't need or want more than 750. I am tracking the car so it will not see more than 600whp and mostly run around 550 as there is no need for more. The reality is most people don't have a clue about how much power 550 to 600whp is. I have learned it is enough and anything else is fun but danger is staring you in the face at every push of the loud peddle.

IPP doesn't have a great track record. If it lives long it will be a miracle. We shall see.

Completely understand the logic just due to the fact that I'm probably more than a couple seconds a lap around a technical track on a 600 then I am on a literbike. With my build where it is now I'm pretty sure it's well into the 600s on map 2 and touching 700s on map 3 considering the level of boost , C2 cams, 10:1 compression and the 6870. With my Map 4 if Seb chooses to go with the 18psi that would more likely than not be a "Because it can" map. Maps 2, 3 are already E85 only maps and part of the reason for the cideo is because at WOT in 3rd I'm leary of looking at the wideband and not the road. We'll see what happens when I get him the vids.

solidus · 02-05-2019, 07:56 PM

I balanced that and considered what had been said prior to building. And basically I called Kyle out on it when I spoke with him. Listening to his side of the stories and then reading the people's complaints it made sense to me but thats my risk. When actually knew the other side of the story and then re read the peoples complaints it all made sense. So far my motor is humming right along and the only complaint I have is ordering Cosworth
head gaskets and them not being available.

You are good. I was talking about the guy making 9xx hp. Those motors have to be perfect and some of them still don't make it long.
Bullit's died, CarbonZ's died, Seb's first attempt died, etc.
I don't care to be part of that crowd.

solidus · 02-05-2019, 09:07 PM

He's not the kind to go out and blast around with 900 horses. I think he'll leave that one for the record books and like many of us just be happy knowing.

I have plenty of fuel and plenty of turbo to make it happen. I am just trying to stay in the safe zone since I don't have an
intake and wonder if I will have head lifting issues myself.

Matt diapola he isn’t really active on the forum much
