2017 SM (Street Mod) Autocross Discussion

Seems the STU guys are far more organized than we are, maybe they are just less busy fixing their "stock" cars . Normal late silly season questions, whats new for you?

I'm working on in no particular order:

-Billet Control Arms to find a proper AutoX Evo caster limit
-Aero parts, will be a Ciro wing and home made splitter. Maybe get Meathooker (Carl) to build me something carbon from my template...
-Wiring in Racecapture for datalogging and working on some thermal sensors for testing caster/camber limits.
-More developments for SSB. After controls arms are finished need to finish brake ducts for those track folks. Where to go after this? Guess this year will have to guide me... Maybe rad splitter mounts?

Major events I'll be at:
-Crows Pro solo
-Packwood National Tour
-Packwood Pro solo
-SCCA Solo Nationals.

Alright, lets get this season going now!

Rebuilt tcase. Rebuilt trans. Other trickery to try and make the drivetrain last longer. Make SM reliable again!

Saw your tear down, you certainly work that drivetrain harder than I do sir! I run those leisurely 1.7 60fts with a single plate just for the reason of keeping things one one piece. Are you coming to Nats next year?

Let's see......
Goal #1: Get the motor done (finally) so I can get the car back and do the rest of the work I had planned... revamped suspension and some serious bodywork.

Because I don't mind sharing, I'm practically rebuilding the car from the ground up:
Powertrain:
- 2.1 LR destroker (4G64 block, Manley billet 88mm crank, Manley Turbo Tuff 162mm rods, Wiseco 1400HD2 10.5:1 pistons)
- Debated going to a drysump setup, but ended up sticking with an AMS pan w/ Kiggly HLA and a 3qt Accusump
- Full-Race T4 turbo kit w/ IWG Borg Warner EFR7163
- New exhaust... Aluminum w/ turndown under passenger seat area
- Exedy Triple HD
- Debating swapping rear diff to either Cusco RS or OSG
- Debating whether I want to change ecu to either AEM Infinity or Haltech Elite or stick with OEM
Interior:
- Install AIM Pista dash
- Fire suppression system (I'm serious)
- Finally swap stock passenger seat for something lighter
Suspension:
- New spring rates... eventually revalve the shocks
- DallasJ's billet uprights
- Swapped back to stock FSB, Robispec RSB (previously Whiteline FSB, stock RSB)
- R/TErnie trailing arms
- Trying to figure out if I want to change the FLCA to either Dallas' or RaceFab Evo X
- Install new Girodisc ultralite rotors
Body:
- Install rep Voltex bumper/canards, rear fenders, sideskirts, and over fenders
- Make sure my 18x12s and 315s fit... potentially try fitting 335
- Build new splitter based on voltex bumper
- Carbon hood and trunk
- Respray/Wrap full car

So far the plan for events is:
LA Pro (tentative)
Crows Pro
Crows Tour
Packwood Pro (tentative)
Pro Finale/Nationals

All in FS (potentially SS depending on how things shake out)

West coast schedules... guess I will see you guys at nats and the finale.

As for my drivetrain, it is a love hate relationship. I love to launch. It hates me for it.

If there's a practice course for the Pro, you're more than welcome to take a run or two in my car

GD, do work son lol. Careful with the Rep voltex stuff particularly the front bumpers, after modifying it for the 231232th time just to keep it in one piece or mount things to it I cut it up with a sawzall.

seriously my god.

I imagine you guys run out of 2nd at nats courses - any solution to that, aside from shifting between 2 and 3? I'm assuming a finally drive, but that prob kills power

That's why Rjones has a built motor and a not stock frame turbo. He can probably stretch that setup to 9000rpm with some useable power.

I'm revving to 8200 on the 2.3l and on a 25.3" tire. Local events I keep it to 7500 but let it stretch for bigger events if I need it. That puts me at 70.X mph but I think next year I'm switching back to the 285 to get lower and will swap to 4.31:1 final drive ratio which will put me at 72.X mph.

I should probably also pull the motor after this next season (3rd season on it) and just inspect things, replace rings and bearings, re-hone, etc. But its been pretty rock solid so far.

Yeah, the plan is 9000-9500 for the big events... on 315s or 335s (same diameter) that'll get me to 78 or 82, respectively. For local stuff, I can't see going faster than mid-70s, so I'll keep it to 8500 or so, which is where I was revving my standard built 2.0.
