In another thread (http://nagtroc.org/forums/index.php?/topic/62911-mod-list-for-600hp130mph-traps-feedback/) I asked which mods were needed to hit my goal of 130mph 1/4 with a full-weight car on pump gas. Having said that my car spends time in the road course so I need a conservative and safe tune! This car won't survive the thrashing in "dyno queen" tune mode! When I asked who the best tuners were another member offered some suggestions ("Tim Bailey from Cobb, Chris Black AMS, Jack Cecil HP Logic, etc.").

Is there a tuner out there that really gets what it is like on the road course vs the 1/4 mile stuff? I will gladly give up 20whp in exchange for a tune that will keep my engine alive for 30min lapping sessions in 110deg heat! Also, having a smooth powerband, not huge torque spikes is a big benefit to lowering lap times.

My power plan is still the same - AMS catless DPs, Akrapovic Evolution exhaust, low restriction air filters and 2012 turbo inlet pipes. If I am forced to go with 3" intakes and larger injectors I will.

Your feedback is greatly appreciated.

Ben @ GTC is really good and is one of the cheapest around for etunes. Fast communication as well! The guy answers what seems like 24/7, unreal customer service. Have him or someone else create a map for you and give them a heads up when you're going to be at the track. Datalog and send them your logs in between sessions for review.

Where do you live? Wouldn't hurt to have someone that could work with you locally.

Thanks for the reply. Sorry for the newb question but is this the company in England? If so, has Ben done a lot of tuning with US fuel as opposed to the nice stuff they get at the pumps on that side of the pond? I take it he is known as a "track guy"?

Have you run the car stock already in 110 heat and managed to get 30 minutes at the pace you want to run? Depending on altitude, etc. getting 30 minutes at 100% with the temps up at 110 without doing something about additional cooling is tough. Increasing the power is only going to make that worse, and there isn't anything much a "tune" is going to do about getting you 30 minutes if you can't keep temps under control...

 

[GTRheritage]

Chris Black all the way,you will get exactly what you need !

 

[Church]

Personally, I would run the car 100% stock tune wise in a high heat road course situation. Any more boost than stock and your temps will be skyrocketing in only two or three laps....

Chris Black is a great tuner as well. I don't' think you could go wrong with any of the top guys.

This is not hard for any tuner. I have a low boost map (runs richer) from Ben at GTC-R that I use in the summer on road course. The problem is your transmission will overheat in 10 minutes so you will need to upgrade your transmission cooler. My friend here is on his 4th custom tuner and now is on GTC-R and happy.
Things i look for etune is response time ( I can read how good a tune is). I datalog and send the file to my tuner while in the car. I get the new tune back in 10-15 min. Datalog and repeat process. Get done in 1-2 hrs. Some tuner's etune package state they will try to get back to you with 24 hour tuner around when possible. That is a joke to me. You will be pissed sitting there waiting.
If you do your research, I believe Ben has one of the safest tune and method. He start out with giving you a 0 waste gate map and datalog from there. That way you are datalog at the lowest boost setting. When I read my log, i can tell my timing is not as aggressive as other tuners, my mid range boost is capped at 17 psi, I pulled to high speeds with the tune. This is all for safety. While others have run 20+ psi midrange and still doing well, a few didn't.

I trained Ben so of course I would say he is good, but we have no ongoing commercial relationship as he is good enough to not need me

I do not tune these days either, too many other things going on.

Based on data I've seen I would limit boost to 16 PSI midrange (and not go for everything you can at the top, as well as AFR on the rich side and ignition that never normally pulls any timing in hard street use and then perhaps backed off a bit) in a temperate climate on 93 octane running catless for road course (what we would call a race circuit, where you do lap after lap constantly on the limit of braking, acceleration, cornering, tire grip, relentless, a proper toasting for the whole car), AND have the big boost gauge prominent so you can see it flashing if 3 or more degrees ignition retard (-768 knock), AND pay careful attention to transmission and engine oil temps, as well as tire and brake condition. If you drive the car properly hard, depending on circuit configuration and the fine details of course, you will then probably find that the engine gets equally or less heat fatigued than the rest of the car and shouldn't be your limiting factor. A good tuner will be willing to tweak based on data from your road course event and start low and work up. You may end up quite like the sort of tune the 2012 car has as stock, like an off the shelf stage 2 perhaps. Quite a bit toned down from what some run on the street or strip (which you guys confuse me when you call it track as track to me is a race circuit ).

For me these events are not about best lap time, but having fun, stretching myself and the car's limits, but not having a tune that you worry about. But as you say, you really need someone who gets it.

... or strip (which you guys confuse me when you call it track as track to me is a race circuit ).

You're not the only one. I think people who refer to the drag strip as a track, have not been to a road course.

I might be mistaken.

However, when I ran a higher boost 'custom' tune at a track in 90deg temps (track temps were over 100degF), I found I lost so much power VERY quickly. It was extremely noticeable.

I figured I would just jump in here and throw Doug's name into things

Doug has been road racing and tuning trackside for 16 years! He tuned our OneLap of America GT-R to live comfortably at 650whp and stand up to the beatings of Leh Keen during a gruesome 11 day event. We also do e-tunes and trackside support for countless customers.

We believe there is a lot more to a true road race tune then just turning down the boost. Adjusting timing, boost, & AFRs based on different load sites in order to make the car buttery smooth coming of corners and efficiently laying the power to the ground is in my opinion a tuning art form!. Sure turning down the boost and running a little richer will make it safe, but you won't get the most out of your car at the same safety levels.

Hope this helps, and let me know if we can do anything for you, or answer any questions.

Damn... If it's good enough for Leh, it's probably good enough for you.

 

[Cicio]

Damn... If it's good enough for Leh, it's probably good enough for you.

LOL, he honestly isn't an easy man to please when it comes to setting up a car! That man feels EVERYTHING!! He will come in after two laps, get out of the car and say

"the car has a tiny hickup at 6250 rpm and minor aero push in turns x...y...z...fix those things and its worth .8 to .9 secons"

LOL...who knows that stuff?

THEN....he will start telling you how to help fix it.....yeah...amazing guy to work with for sure!

Forged has been building and tuning road race prepared GT-R's since the beginning of the GT-R in 2008. We were the first tuners in the country to craft specific calibrations suited strictly for road racing use. Our Forged GT-R is still running it's factory installed OEM engine even after 350 plus hours of track use. Forged Performance still holds the GT-R track records for Road Atlanta, VIR, CMP, and Sebring so we know a thing or two about tuning GT-R's for track use.

With the current Speed Density Alpha tuning we are doing, power delivery and shifting has never been more seamless. Feel free to PM me with any questions or help needed.
