The weather at the time was pretty good but ambient temps were in the 50's that morning. Now to be on the side of safety, I recommended he run a mixture of c16 because of the inherent nature of Hallman BC's to spike in the higher gears and hold in 4rth.
If the car would not be safe above a certain boost why didn't you just put a boost cut in the ECU?

The only thing about drag racing that I can imagine being tough on an engine is RPM. Sure if you go to the track and up your rev limit beyond a safe limit I can see drag racing being tough on the motor. But how else is it tough on a motor? How is it different than blasting down your favorite road?

I've never read about this but had heard it a few times here and there. Doesn't really matter. Have you tested it?

Why would you assume there isn't a boost limit set?
Secondly, why would his boost cut be set so close to the threshold when he is running a better fuel to compensate for 1-2 lbs that MAY increase with load, gear and or ambient temp?
As a matter of fact why are you even nitpicking something you don't even know the answer to... You know what don't answer that please...Please don't forget I even quoted you.
The rest of your quote I will leave alone. You clearly have very little to argue about nor is it worth my time to respond to.
Good day.

Calm down. Everyone likes to post results of x, y and z. But as soon as anyone asks some interesting questions everyone gets their panties in a bunch. My understanding of the situation is the same as it was before. The car was potentially running a boost level or AFR level that may or may not have been safe on pump. End of story.

Looking forward to seeing this car with a proper fuel system run a great time.

If you had to run C16 on your "pump gas" map, it's not really a pump gas map otherwise you would run pump. I am also very skeptical about you running that MPH on 23psi on that turbo with an A2A intercooler. Sorry, I just don't buy it. The fact that you had to run C16 even makes me more doubtful you were actually running 23psi.

Good time but I'm skeptical about some of the provided details.

From reading this whole thread, it doesn't sound to me like he "had" to run c16. I can imagine a conversation something like this.

op calling tuner from track: dude, it's waaay colder out here today than when you tuned it. Won't the boost go higher? Will I be ok?
Tuner: you'll be fine.
op: maaaan are you sure? brand new engine. Don't want any issues.
tuner: then put in a couple gallons of c16 for piece of mind. But really, you'll be fine.

If there was no c16 in it while being tuned then I would consider it a pump gas tune. Cant really guess at it and allow for when you add race gas. It would have to be there.

He didnt have to run c16, he did it for peace of mind due to the conditions.

Don't worry about my mood. I'm calm. There is a difference between asking interesting questions and being stupid. The latter applies to many of your "comments"

Ahh another conspiracy theorist. Welcome aboard. Make sure to buckle in. Listen or should I say read closely. Reread many of my posts and this thread again. It is the same car that ran the SAME mph on pump gas weeks before.
Honestly I could care less at this point what you believe. Its his car, he wanted to post about it and he knows what he is running. This isn't the first car that has done it. Our TA car did it on 17 psi. and only pump fuel. Again could care less if you don't "buy it"
Your assumption that you would need to somehow run some magical intercooler to make modest power at a modest boost level is ignorant in itself.
If we would have known that 133 mph at 23 psi is some kind of record (It must be with the two of you stroking it in this thread) then we would have promoted this in some other fashion. Thanks for the comments. Keep em comming.

It is what is. The run was done with a race gas mix. End of story.

Doesn't stop me from thinking it's a great time and from the looks of it the car can run a whole helluva lot better. People need to learn to seperate questions from criticisms. Also there should be a level of respect given to simple curiousity and questioning. DTM if you it makes you feel better and smarter saying my questions are "stupid".. good for you. I don't do this stuff for a living so I should hope you're more clued in than me. You could ask me question about my trade and I could insult your ignorance all day long. But why would I do that?

By the way, remember that pump gas dyno war you started with Buschur?

Whatever happened to that? What is the fastest pump gas customer car you have turned out since then?

That car went 10.83 @ 134.65. Still many driver mods needed. It's in peices right now. Wait 'till next year.

Well that is impressive. Do you know where that thread is?

Considering you quoted the owner and driver of said car I would assume you should be able to accept his statement for what it is.

Joe knows full well that what's holding him back at this point is his own driving. I think he spends too much time in his Prius!

Joe discovered what was holding him back this season. The best is yet to come. Looking forward to the next racing season.

I think people like you need to understand the difference between criticizing and asking questions based on ignorance. You and I have been around the block many times over. People can simply read your antagonizing posts from many moons ago all the way up to today. Mine have always been factual in nature and answering what I can. So please don't come unto this board and act like Marry Poppins. I have seen the other side of the Cain...
