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.

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.

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.

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

Did Forged Performance tune his car? I saw something on Instagram about a 2.5 FI TT car.

Actually I am glad he made that much. Why, because MA's dyno reads low and folks were already asking for a Dynojet run of my car and it wasn't even finished yet. I personally don't care to go through the hassle of running the car on someone elses dyno. At the end of the day if I am happy that is all that matters.

Yes forged tuned it

^^^ This! I really don't care about the number as it will be enough period. I simply want a platform that will give another five years or better of being beat to death on the track and some half mile flat out run events.

I'd like to do some half mile events also.

Here's the numbers I copied from the ExCel chart I made to convert the MA-M DynoLog to the DynoJet numbers.

Why Our Mainline Dyno Produces More Accurate Results

Inertia Dynos - like DynoJet dynos, measure power based on the length of time it takes to "spool up" two heavy steel drums within the dyno. Horsepower numbers are much higher because they are based on distance traveled / acceleration rather than force, at least 17% higher than load bearing dynos in our experience. Cruising air / fuel ratios are generally richer because they are based on wide open throttle conditions.

Load Bearing Dynos - measure power based on the force applied to the rollers when the dyno brake is applied. Loading the engine gives us the ability to hold the engine at various loads for driveability tuning and maximum fuel economy. All Mainline dynos are load bearing dynos.

ACCURATE, DEPENDABLE, REPEATABLE RESULTS
The Mainline Dyno is widely described as the "no fudge" or the "unfudgeable" dyno, and is the obvious choice for dyno operators who choose an honest approach to business and do not want to be caught up in the debacle about why the same car can get differing results on the same brand of dyno, why the same car can produce inconsistent results using different dyno "modes" or even why a dyno needs different "modes" for 4, 6 and 8 cylinder vehicles.

The Mainline Dyno deserves its outstanding reputation for producing the same results from dyno to dyno, as a scientific approach has been taken that provides the highest degree of accuracy. No need for a special operating mode that reduces the ability of the operator to affect the results. No menu options for the dyno operator to "modify" results. There are definitely no cheat modes and no smoke or mirrors on the Mainline Dyno.

Car has been delivered to MA. DC traffic is hell. Brian has a couple of vehicles to tidy up before he goes full out on mine.
It's in good hands.

I figured you was in the process of dropping it off. Because you've been quite. :rofl2:

The Clock Starts === NOW ===

He’ll be fine; ready to see that “Beast” @Zdaz this year! :tup:
Spooler, have a safe trip back home... if you aren’t back already :tiphat:
Glad you had a warmed up window, to get it up the road :driving:

LOL, The clock started last year on March 6th when I started this thread. I can see the finish line from here.

Already home, I got to meet everyone and talk about the build. I got lucky we had this freak warm up period. That worked out in my favor for sure. Hoping the car will be done the end of April at the latest.

Fudges. I’m going to be eith my car for a long time

?????? eith ????? without???

Tell them to pay for it

Lol without

Brain did not let it slip his mind that I have a 1975 280zt. He was asking me questions about it on Friday. LOL He wanted to know if I was dedicated to the L28 engine. I started laughing. I would really like an RB26 for it on a standalone. Talked with the wife about it. Already talking about another build before this one is finished. Some things to ponder for sure. One day, this will happen.

Finish one project before moving to another. Otherwise the first will never get finished. :facepalm:

RB swap the 370. Put the VQ in the 280.

The 280z project will be several years away. LOL I have to recover from this one first.

Negative. LOL

By the way. I won't be posting that project on the forum anyway. It will just show up at Zdayz one year.

Work has begun on the car. MA's not wasting any time.

I am having a couple of things done differently. Cause that's how we roll. You'll see in the end.

Waste gated through the hood?

Drivers side A/C vents

LOL, I hate how that looks on a street car.

Nah, I got an old "Don't tread on Me" sticker for the back bumper and the centerfolds taped to the headliner.

Spooler you should jump on the Ron Davis bandwagon. Cost little
More then that csf.
