Yeah I was skeptical about the diff as well, but not having had any experience with FWDs I thought id give it a go, and boy did it make a difference; like night and day.

The control coilovers are quite soft so the car loved to bake the inside wheel on exits out of tight corners no matter what I did. With a welded diff you are able to use the power to pull the car around the corner, its truly incredible. The fact that its welded doesnt even really affect entry so long as the suspension is set up right with driving style to suit.

I could have fitted an LSD ($1000+ from US) but for the money I dont think I need to try it, and the car is already fast. Welding the diff was worth over 2 seconds at Winton with nothing else done.

Do they weld diffs in Excels too?

In tas the excel cup won't allow welded diffs or a LSD, other states might allow it tho, sounds like something I'd do if the rules would let you.

So the weekend went good , I had a blast! Got nails hard in the rear. Bloke behind me had no brakes at the end of the straight at Symons plains his left brake nipple wasn't right and this was the end result,

But if bad luck but it's all good I guess that's racing, bring on the next round [emoji106]

Looks like a normal Excel racer now.

That sucks. Id be pretty annoyed if someone did that to my car - thats bad racing imo. And wont be cheap as you cant just unbolt the rear quarter to put another one on!

Each driver has a responsibility to race safely, but obviously staying close to you to try and pick up a position was more important to him and as a result plowed into you.

It is however an entry level category like PC so its no surprise :-(

i know a few people in the pulsar challenge, put up a pic of your car matt!

its interesting that most people opt for N14's due to price and independent rear suspension, but often the top of the field are N15's. bit of tweaking to the beam and they handle well.

and yeah, lots of people saying good things about the welded diffs. Mfactory release a helical diff last year which is around $700usd and the other option is discontinued Nismo which can fetch around $1500 secondhand

[Skepticism]

anyone here running in Pulsar Challenge?

Apparently you can build one for around $5000 and race meets should set you back around $500 a round. was thinking of splitting the cost with a mate and running the enduros with him.

keen to hear people's experience with them!

Damn... that's actually really cheap. Way, way cheaper than I thought. I need to look into this!

edit: apparently you can bore out the engines and such. that would tend to increase the cost, lol. what % of competitors have done this ? how do they enforce some of the other restrictions on internals?

What? You sure? Very little modification is allowed.

[PN-Mad]

Correct.

Only standard rebuild tolerance is accepted. You can bore 0.6mm out the block.

You can take 0.25mm off the head. But the compression has to be with a specified range.

It's all in the regs.

I wanna get into this but no fabrication or mechanical skills, or track time, just some decent pace in iRacing.... long way to go, hehe

Here's a little vid off my in car footage, ( sorry I don't no how to upload the go pro footage so I filmed off my phone) in the excel cup,
