Building a $50K Track Tool to beat $500K Track Tools

Sears Point Raceway 03/07/2015 Report

I was out at Sears Point Raceway this past weekend (03/07/2015) for a TrackMasters HPDE. The last time I was out there was last September when I blew a head gasket in the afternoon session so I had some unfinished business. It was a sold out event with all the usual suspects including two beautifully prepared Ferrari 458's, one Challenge Car and a Speciale. As usual, a huge contingent of Porsches, including four GT3"s (2 RS's) and several very nice air-cooled 911 race cars along with a couple of 914/6 GTU race cars.

NSX's were well represented by Don's (nsxnut) sweet S/C NA1, Armando's twin turbo Driving Ambition prepped NSX race car (500+RWHP/2200lbs) and myself. We had a good turnout of NSX Primers in attendance as well, with Roman (Solidol), Harry (SFNSXguy), AJ (JINKS), and Jorge (quicksilver55). It was so great to have a nice representation of NSX's. Thanks for coming out guys and supporting the cause.

My goal for this event was the same as always; Drive to the Track, Kill'm All, Drive Home.

Here in Northern California, the Porsche 911 GT3RS is by far and away the weapon of choice for HPDE track days. These are amazing cars, packed with 50yrs of factory racing development including; traction control, launch control, stability control, 4-wheel steering, center nock-offs with huge tires and wheels, massive Brembo carbon ceramic brakes etc etc.

Targeting these cars is no easy task. They have a definite horsepower / brakes / tire advantage over my 2800lbs, 400rwhp NA1. Weights are roughly the same, depending on set-up. Patients is the name of the game when stalking these alpha-cars and their alpha owners. The typical GT3RS driver is at the top of the food chain in the Porsche pecking order. They pit together and keep to themselves to the most part. On track, they don't use their mirrors much and the last thing they are expecting is a vintage ricer to be keeping pace with them. Passing GT3/RS must be done very carefully as they rarely give away a position on track without a fight. Having a HP disadvantage to them only makes getting past them that much more challenging. My usual method is to stalk them for a couple laps before applying just enough pressure to either force a mistake from them or hopefully get a point by. The video below is a typical encounter with a GT3 driver. I had been stalking him for several laps and he was clearly holding me up but he refused to yield the position. He was clearly over driving the car and his tires were going off when he finally points me by, only to nail the throttle at the same time. A typical #porscheprickmove. After that my fangs came out and I went in for the kill and finally got past him by late braking him into T4.

The fun just began when I finally got past him and on the next lap Armando's 2200lb. 500+HP twin turbo NSX racecar blew by me entering T11 then got real loose exiting T11. Later, on the next lap, he attempts to pass a couple of backmarkers between T5 & T6, drops a wheel off and does a full 360 spin! Just when I thought things might calm down a little, a real yahoo in a 240SX packing a smallblock V8 squeezes inside of me entering the T6 carousel, then exiting T7 he over-steers and goes careening off track! Pretty much sums up the weekend.

By the end of the day I had accomplished my goal of passing every Porsche, GT3RS or otherwise on track. Obsessed? Maybe a little
:wink: but its good to have a plan and a goal. The car ran fantastic all day long with absolutely no issues what so ever. Just like Honda intended. The 6th and final session was my quickest, mostly due to that the moving chicanes had called it a day leaving me with a nice empty track to play with. Good times!

Hi,

nice driving :wink:

those P guys do know how to be annoying.

Just a question... i notice that one corners, you make very harsh
corrections on the steering, instead of staying smooth and only
correct when you feel the car starting to go off. Why do you do it?

Thanks,
Nuno
 
Nice video, love to see how you chase the GT3 :)

Have a question though, what diameter is your Momo Competition steering wheel?
I am looking for another steering wheel for my NSX, the OEM one simply is too large in combination with my Recaro seats but I am undecided on what wheel and which diameter to get.
 
Glad you guys made it out in one piece. I love the concept of open passing a few of the advanced groups I run with let us do that but I have yet to have anything like that happen in a single session. Maybe my entire day combined I might have as many things happen as you had in that single session. Amazing.

Still looks like a blast, glad to see the car back on track.

Did you do anything about your IATs?

Thanks Nuno, indeed they can be a real nuisance. I'm not quite sure what you are referring to. I was being held up by the GT3 for most of this session and was never pushing more than 7-8/10ths. As a rule, whenever I have a passenger onboard I try to keep it well under the limit. My tires for this event were the medium compound BFG R1 and on corner exit the fronts would tend to drift/slide before they let go so I'm having to make quick corrections for that to keep the back end from catching up to (and passing) the front end :eek:

Thanks MvM, I love chasing down GT3's Its what I live for :cool:

IIRC the wheel is 330mm Sparco, love it. Really helps if you've got race buckets and long legs.

Way to go Berto! Thx Roman for the pix. Clearly you have more skills than the P-guy. You were wring the NSX and he was driven by the GT3. 2200 lbs @500hp :eek: wow.
Thanks Tim! thought that might get your attention you weight weenie! :biggrin:

Thanks Dave, super fun day at the track, but also super exhausting having my head on a swivel for 6 - 20min sessions. The yahoos were definitely out in force.

IATs are still an issue but I think I'm wearing Shad down on building me an inter/aftercooler. Fingers crossed.

Thanks for the update. I was wondering if a 330mm steering wheel allows you a good vision on your dash instruments?
Unfortunately, I am not that tall but so far, I fit.

Depends on where you adjust your wheel. I'm 6'0" 170lbs and it works great for me. YMMV

Oh, 170lbs ...... I remember those days from long ago. :biggrin: I would be happy if I could get back to 200.

The Divorce Diet: Eat whatever you want, whenever you want... You just don't feel like it...:frown:
 
I KNEW you put the wt. in to get my attention!:biggrin: well, I don't have skills like you do so I need all the help I can get. The ONLY category I can beat you is MPG...LOL:eek:
I don't recognize MPG. I use FPG... (feet per gallon) :tongue:

Ha, too funny! I just went on the Divorce Diet v2.0 myself. :biggrin: First I gained five or so pounds 'cause I felt so crappy, then I met a new lady and lost 20 pounds because I felt so good, then we broke up and now I'm back up two or three pounds. But I swear I'm not going back to 210 pounds. My race suit didn't fit! Plus I don't want to be single forever!

"Vintage Ricer" Bwahahahah!

But seriously: this is one of my favorite NSXs in existence. Great post.
 
Drove a 458 and Huracán in anger at the local track this weekend. Wow, incredible machines. The amount of engineering in these things is remarkable. The Huracán pulled harder than anything I've ever driven. It's going to be difficult to build an NSX that can rival those cars. Just the amount of performance electronics is something that will be near impossible to compete with.

They're heavier, particularly the Huracán, and that could be a huge differentiator. I guess the fun is in the trying! Robert, how are you doing against the 458s on track?
