Obioban's 2005 IR/IR Coupe

Does the house run on a V10? What about the E60

[heinzboehmer]

Car projects have been pretty slim, because I'm building a house...

... should I do a house build journal on here? Everything about the house is unusual construction methods, but this is a car forum, not a house forum...

I'd read through it. Especially if it includes some garage stuff

I was curious to know whether or not you ever got upgraded fuel injectors to support cams and CSL intake. Seems to be a popular subject recently. Looks as though 550cc injectors are being recommended.

Any thoughts?

I have not.

My power curve isn't flattening up top, and my injectors aren't being run at 100%, so I don't see any reason to.

Any new pics of the IR/M it seems like the old pics won’t pull up?

Seems like the roof would disqualify you

Seems like a lot of the JDM guys get by on body panels that were optional on higher spec materials, ala cf roof on the csl. I think I can get in under that.

Seems like my car would qualify for their street class:

i've never heard of fender vents / speed holes referred to as "track life style fender cutouts" until now

[Obioban]

I would hope they update this rule to match inflation.

… strange statement to make on a racing class 🤔

[repoman89]

Shouldn't

Until next year

[Obioban]

Inflation adjusted MSRP limit of $75k is probably going to disqualify you based on the quoted rule set

Seems like my car would qualify for their street class:

STREET


STREET is intended for vehicles with minor bolt-on modifications only. This is our enthusiast class and is intended for advanced HPDE drivers and vehicles that are daily driven street cars, or at least daily-driveable. This class is designed for naturally aspirated 3, 4, 5 and 6 cylinder vehicles, and forced induction 4 cylinder vehicles. V8 Powered cars are not allowed. Rotary (turbo or NA) vehicles are also allowed, if all other rules are followed. Electric cars may potentially be classified in street, based on accelerometer data traces compared to other competitors in class. Street cars must be registered/plated and drivers may be subjected to a “take your spouse for ice cream” impound.



Vehicles with inflation adjusted MSRPs greater than $75,000 (as of 2022 rules publishing at the end of 2021) are specifically banned.

• All vehicles must retain stock chassis with no fabricated modifications of any kind.
• Doors, fenders, quarter panels and roof must remain OEM material.
• Bolt on alternate materials may be used for Hood, Trunk and Hard Tops.

I guess its a semantics thing, but with Nasa we call time trials what you have described as a time attack. I quite like that format, which is basically a DE with (usually) skilled and courteous drivers who are going for hot laps and doing their best to not get in the way of other individual's hot laps. I will usually "double dip" nasa weekends in TT3 and ST3 to give myself the best odds at winning tires.
