Tuned In

There was a time when fanny packs were a status symbol, a shag cut had nothing to do with the backseat of your car, bricks were considered aerodynamic and Nissan was a brand no Datsun owner had heard of.

This Open Class 1971 Datsun 1600 (510) time attack weapon is keeping the best part of those things alive, with plenty of modern upgrades. Powered by a, ahem, 'Datsun' SR20 pushing 350kW (470hp) to the wheels via E85, 25psi (1.7Bar) of boost, a BorgWarner EFR7670 and a Samsonas 6-speed sequential, this flying brick is a credit to all involved especially owner/driver John Healey of V-Sport Australia.

Electronics are handled by an EMtron Kv8 ECU, MoTeC C125 dash and PDM 15. John is getting as much value as possible from the PDM which is about at its limit powering everything in the car, including the electric steering setup, something we don't commonly see used in time attack builds.

The SR20 is a bit of an unknown, with John having had some head work done, but the bottom end left as it was purchased secondhand. A Bosch DBW throttle body to assist in rev-match downshifts to help avoid some of the issues that are well known to kill SR20s, and along with a 7,800rpm limit, so far so good!

A universal Sydney Composites aero kit has been fitted, and as you would expect of someone from V-Sport, the brake package is on point with the Datsun 510 utilising an AP Racing pedal box and 4 pot front brack calliper, Brembo 4 pot rear and pretty much the biggest discs you can squeeze under 15" wheels.

Christian from Nitto Performance Engineering answers this question and more from the World Time Attack Challenge paddock in relation to high-quality aftermarket head gaskets, including some of the design and manufacturing processes that go into ensuring the gasket can not just contain your combustion charge but also your oil and coolant, which are often overlooked yet are just as important.

You can also gain some quick insight into whether reusing a head gasket is generally a good idea given the time and money that goes into a performance engine build, as well as some other knowledge bombs on head cylinder sealing in general.

Field Report: Do you reuse your head gasket?

*** We’ll be taking a break over the Christmas/New Year period and will be back in action mid-January.

That means that although there won’t be any new episodes for a few weeks, we’ll be taking another look at some of our favourite conversations from 2024. ***

Over the last few years, we’ve seen a massive increase in the availability of ultra-high-performance billet parts — especially blocks and heads. This week’s guest, Chris Smith of Crest CNC, was one of the pioneers of this practice in the import category, but now he’s branching out from the 5-axis CNC and heading to the foundry to produce cast engine parts — we find out why.

Chris Smith came up in the trade as an engine reconditioner, before buying his first CNC mill and starting on a career path that would eventually see his business become the go-to supplier of billet blocks and heads for some of the world’s fastest racers, as well as the odd OEM manufacturer.

This week’s conversation first jumps into the ins and outs of metallurgy and tribology (which, by the way, is the study of interacting surfaces in motion). We learn the difference between various materials commonly used in high-end performance applications — like 6061 and 7075 aluminium, for example — as well as the pros and cons of different 3D scanning tools, coordinate measuring machines, and CAD software.

The conversation then steers itself towards the weaknesses of both Nissan’s VR38 and Subaru’s EJ motors, delving into how failures occur and how Chris addressed them with his billet block and head offerings. While on the subject, Chris also goes into detail on the advantages and disadvantages of wet and dry cylinder sleeves, as well as the reliability and maintenance requirements of billet engines.

This naturally brings us to the elephant in the room — why a billet engine specialist is now offering aftermarket cast engine products. Chris lays down the reasons why it’s a good idea, and takes pains to explain how aftermarket cast is very different from the cast blocks and heads that come off an OEM manufacturer’s production line.

Are aftermarket cast engine parts the way of the future? Listen to this episode with Chris Smith of Crest CNC and come to your own conclusion.

Revisited: Billet Isn’t Everything — The Rise of Aftermarket Cast Engines.

Ever wondered if a wheel’s stiffness can affect camber or how rotational inertia plays into vehicle response? Eddie from Titan 7 explains their commitment to minimizing deflection, reducing tyre creep, and designing spokes that strike the perfect harmony between strength and aesthetics.

3000HP+ 4 cylinder drag cars, EKanoo's World Record breaking 5 second door slammer, LMP3-turned-Pikes Peak hill climbers, 460mph++ land speeders, the list goes on and on, and this is only a portion of what Shane Tecklenburg, aka Shane T of '@TunedByShaneT' is and has been involved with throughout his career.

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

Let's dive into some of this along with how his career really got rolling leading to his involvement in projects like this and so much more leading Shane to be one of the most passionate and pointed people we know in the industry.

Also discussed are some of the specific challenges of tuning a car to race at Pikes Peak international hill climb which see's competitors finishing at over 14,000ft. That's high enough for aircraft to require the use of oxygen in the cabin.

NOTE: Some scientists claim swearing can be a sign of intelligence, and if they used Shane as a subject we'd say they're right, so be warned Shane has a 'diverse' vocabulary that may be unsuitable if you're still convinced that your children will never hear such words or use swear words themselves 😅

We will dive into what Myles' does is at English Racing to help make sure customers are realistic of the demands of a high performance build for the street and or track, and how he transitioned from a customer service role to building his own 1400WHP Honda Integra.

Myles' 'Gringotegra' is far from any normal Integra, with 1400WHP, a 4WD conversion and many other modifications. We talk reliability issues such a build presents and how he manages to overcome them in order to daily drive this insane Integra.

Also touched on is tuning philosophies around half mile drag racing and how they manage torque management on a 2WD vs 4WD cars. Another point discussed is how much harder on the engine is a half mile drag race compared to a quarter mile drag race.

Also talked about is what goes into developing an industry leading ECU, what functions EMtron is bringing to the aftermarket world such as 'Geo Fencing' and 'Throttle Mass Flow'. Scott also gives us insight into the future for EMtron, what sort of development path is the ECU brand heading towards and what potential new products are in the pipeline.

Some other topics also discussed in this in-depth episode focus around Chris's trackside support role he offers to some customers, how he guides customers to make the best choices they can for their ECU and tuning upgrades for their application, when reflash tuning is better than fitting an aftermarket ECU, the future of reflash tuning, what motorsport disciples are the hardest on gear and much much more than we can fit in a description, so have a listen.

006: 'I Just Want Big Flames'. Handing Customer Expectations and Reality - Chris Wall.

Even when budget is not a limiting factor, why might a team choose to use a factory block over an aftermarket billet one in a Time Attack build?

With a 2.2L stroker 4G63 MIVEC build featuring a custom billet crank, rod and pistons, Benjamin Perry of Benchmark Solutions explains why a billet block was not a consideration for this build along with covering some of the upgrades the Global Aircraft Services Mitsubishi Evo 9 has seen in order to remain competitive in the ever-popular Open Class as the World Time Attack Challenge.
