Re: wet sump engine oil control, a thread.
it is, it would be great to see if/how much a crank scraper helps. I'm unfamilliar with the oil drains on a LQ1, anyone have pictures of how the heads drain to through the block? There are drainback passages on the outside perimeter of the block at end of the heads. Where the passages enter the cra...

Re: My 3.4 DOHC powered red and black camo '88 Fiero Track Car
My big project for April/May was to finally add some true datalogging capability to the car, and put a cherry on top of the interior. I picked up a Joying Android head unit, and permanently installed a USB CAN interface inside that works with the RealDash app --- a professional quality digital dash ...

Re: wet sump engine oil control, a thread.
Please post up the results! I'll be very interested to hear them. It's worth mentioning that oil control applies to more than just the sump, I assume you have a PVC system of some kind? It's possible that the PCV is pulling oil from the valve covers, do you notice any knock retard or knock sensor a...

Re: wet sump engine oil control, a thread.
I'm close to proving my power loss after high G right hand turns is actually an oil control / windage problem. I haven't noticed a loss of oil pressure on right turns, although I've added oil pressure logging and will know better this weekend. What happens is this: after exiting a 1.3G right turn as...

Re: The Mule rides again (sort of) - pics.
Wow! On the '88 there is a steel brace that goes from the base flange of the master cylinder to the combo valve, which is bolted through to the left frame rail. Do you have that? I eliminated it with my master cylinder swap... I might need to bring it back...

Re: The Mule rides again (sort of) - pics.
Are you sure it's not the brake booster flexing? On my 88 I get 0.035" vertical deflection of the brake master cylinder with full pedal force. As much as I can generate. 150 lbs? 200 lbs? did you check horizontal deflection too? this is an interesting observation, I know in my car, it appears ...

Re: My 3.4 DOHC powered red and black camo '88 Fiero Track Car
Update for April 2024 After I had some autocrosses under my belt and a lot of new confidence in the car, I booked a weekend with NASA at Buttonwillow Raceway and got to work on the last few major items on my track prep list. First on the list was recovery points. I checked my front tow loop and it ...

Re: The SERIOUS Wheel & Tire Thread
Awesomesauce that you got it up and running with those! Do you still have Koni rear struts? Yeah still running underdamped Koni reds set to full stiff %) How much wheel-to-strut clearance do you have? I have C5 Corvette 18x9.5-61 rear wheels with 25mm adapter. Based on that fitment, an 18x9.5-35 wo...

Re: Staggered tire fitment.
Power is a factor as well. C5, C6 & C7 Corvettes are almost exactly 50/50, but run a significant stagger because they have a lot of power. For a low power ride, stagger matching the weight distribution is a great bet. Like the 50/50 BMWs, the Corvette racers run square for best performance on t...

Back to doing autocrosses and track days in my 88 this year. Since the last time I tracked the car, my setup has changed from 215/275 staggered Hankook RS3s and 12" rotors with stock calipers, to 265/315 staggered Nankang CR-S, C7 Brembo brakes, custom front and rear uprights, and Conti MK60E5 ...

Re: Any Fiero road racers running tube chassis cars?
Nice cars! I love the notchie.
The Fiero racers I know are running cars based on the stock spaceframe. There must be a lot of tube frame cars out there but I rarely see them come up for sale.
What tracks do you go to?

Re: Staggered tire fitment.
87 Duke with a 5 speed is 43.5% front, 56.5% rear so an ideal stagger would be something like 195 front 255 rear. Given that a front suspension tends to not work as well as rear since it has to turn, you could bump it up to 205 or 215 at the front and probably not be too front-biased.

Re: My 3.4 DOHC powered red and black camo '88 Fiero Track Car
New seat! Got a Sparco Evo to replace my very very old (1999 build date, I think) Sparco Rev. I also put new upholstery on the Corbeau A4 on the passenger side. Went from red seats to black ones. I might do custom upholstery at some point to spice things up a bit, but I'm liking the black for now. I...

Now running 315/30/18 rear and 265/35/18 fronts on my 88. The tires are Nankang CR-S (200tw). The wheels are Apex SM-10 18x9.5 ET35 and 18x11 ET35. I'm running a small (3 or 5mm) spacer in the rear to clear the trailing link, which is lowered by 45mm at the upright compared to the stock. Otherwise m...

Re: Daily RX8 with LFX?, lol
I drove some special edition but otherwise stock MT RX8 once and it was an absolute blast. Punches way way way above it's pay grade. Probably one of the best car chassis ever made. Just needs a good reliable engine with at least 300hp. An LFX/LGX swap would be awesome.
