How High do You Go?

[ckendri]

I see a lot of guys on here talking about shifting at 7500 or higher. Do guys with 15-17 cars and PD blowers or otherwise run their cars up that high? Stock valve springs? I don’t hear much about blown motors except for guys making 1000HP on a stock bottom. I shift out around 7200-7300. I realize my VMP may be running out of steam at that point, but I’m curious how high guys go with their stock motors.

My VMP '15 shifted at 7,800 without a problem for 25,000 miles worth of daily driving and lots of weekend abuse, stock opg/cs as well.

What did VMP tell you? They tuned it I assume. So they know what the setup is -- that you failed to share when asking for second hand information btw. So go to the most direct source to answer your question. They are good people who I have used on two separate builds. So take the advice of Justin and Joe and the gang down there.......assuming they tuned it since you shared nothing about your setup.

First hand 411 from the tuner who knows the setup and does it fora living by far out weighs the varying novice opinions you will get from a forum. pick the phone up, and call them. Smart phones are for more than texting and internet access or they would be called tablets.

I have used them for 2 previous builds with confidence.

Ran my Vmp and my whipple both to 7700-7800

Thanks for all the input so far.

Sorry ugstang17, I didn’t mean to come across like a complete moron (only a 1/2 moron). I was asking the question out of curiosity, and not for “what should I spin mine up to.” However, I do agree with all your points. Great guys at VMP, and I would definitely ask them what they would recommend. I was just reading through posts and started noticing a trend where a lot of people were running up to 7700-7800, so I thought I’d ask the question. I’m amazed at what these motors can take, and was just collecting information. I’m a nerd like that I guess.

Just for reference:
2016 GT
VMP Gen2r w/ 79mm pulley
Twin 60 TB
Installing twin 68 TB
Installing a PMAS CAI
Fore -10 feed -8 return running E85
Currently installing Kooks 1-7/8 headers
Currently swapping to a TR6060

Plain Jane setup it seems like.

You're not a moron and I never meant to suggest that. I just find it best to go to the source on topics like this.

Plain Jane my eye! LOL! That is one heck of a setup. You can bet they have the rev limiter set in the tune where they know it will be safe, but like you I would want to know where it is so I don't bounce off of it all the time. If you have Fore from end to end and running ID 1050x FI's or larger with the 79mm pulley and your fuel pressure is set right I'm sure that they have the rev limiter above 7500RPM. However that is before going to the 68mm Twin TB. So you will need to ask them again when they update the tune for that. You should go to Amazon and order Greg Banish's book 'Engine Management - Advanced Tuning' and read it through. It's an awesome read and great reference book to refer back to. I've read it through twice and refer back to it a lot. My background is more electrical/electronic with mechanical basics so for me the book was an awesome recommendation from a guy on another site who tunes and suggested it to me. I was able to understand what Joe and Justin and Alex (who has since left) were talking about when we were tuning my car remotely. It also helped me to better relate to them issues I wanted addressed in emails along with datalog files. Made things a lot smoother.

If you ever get the chance, if you haven't, go to an NMRA event and watch the stock Coyote class run. That class runs a fully stock Coyote with a special tune made for the class by FRPP as I recall. They can put the engine in any Mustang they choose. They are not allowed otmodify the engine internally in any way. The engines are sealed to insure that they aren't tampered with. The cars ECU's get reflashed with the default FRPP tune by an official athe beginning of every round to insure that there is no cheating. They can run any type of fuel they choose however as I understand. The cars are shifting above 8000 RPM and leaving on the rev limiter. They beat the crap out of those engines with the majority of them running mid 10's or faster N/A. So yes these suckers can spin up. but again the RPM limit on a boosted setup will be the fuel system with respect to the boost level being targeted.

I may be considering pulling the T67mm VMP TB on mine and going back to a 60MM. IF you plan to sell yours let me know. I may be interested if you want to part with it.

I’ll definitely check out the book, and thanks for the info. I know zilch about tuning, and need to know more.
