Maybe. Ben's trailing arms do seem pretty light. But I do think my shock is a little more compressed at ride height than is ideal. I think putting the upper mounting point in the frame is definitely the way to go. It's just easier for me to machine a part than to cut and weld back there.

Just took it out for a quick drive. The rear end feels so much better over bumps.

I have drop brackets for the trailing arm to fix that.

I actually measured my shock at ride height and it's at 14.5", which is what ride tech recommends.


My buddy upgraded to a double pumper Aeromotive setup and gave me his Walbro 525 for a deal. At 27 psi of boost pressure I was seeing a 83% duty cycle on my ID1300s, so I wanted some extra pump headroom for when I turn up the boost this summer. Since the pump requires a bit more current than the 450, it transfers more heat to the fuel. To counteract that, I used an old oil cooler I had lying around as a fuel cooler.

I've never had vapor lock with this car, and I hope this cooler prevents it in the future with this pump. I've got a few more things to do before Davis, but I should be able to do it in time.

Ever since the fuel pump upgrade, I've been looking at my injector duty. It's not ideal.



The screenshot isn't great, but the lower plot is injector duty cycle (red) and boost (yellow). Injector duty peaked to 98% at 27 psi. What's weird is that after the gear shift I hit 33 psi, but that only required a duty of 85%. The spike corresponds to a difference in wheel speed between front and rear (upper plot). I'm not sure why the engine requires more injector duty during wheel spin when then engine isn't loaded as much. Can anyone shed some light on this?

I don't really want to, but I might have to upgrade to some 1700cc injectors. The above is all with a base fuel pressure of 60 psi, so I can't really increase it with the boost pressures I'm running. Ideally I'd do staged injection, but I don't have the available outputs on the ECU for that, and it would be way more expensive than a set of injectors.

Does anyone here have experience with idle quality on pump gas with ID1700s? I try to keep a mix above e60, but on road trips and stuff I use normal pump gas, so I'd like to know what I'm in for as far as idle quality.

What size lines to you have? What is the fitting situation at the sending unit?

I have -6 fittings brazed on the sending unit, and use -6 line with the stock hard line.

The bend in that sending unit is so small. Like the size of a 5/16ths fuel line

That's true. I should make my own with a different fuel level sending unit and big hard lines.

yep, the fuel system is only as good as the smallest part of it.

Do bulk head fittings and a -8 line for the feed. Make sure you're getting charging voltage at the injectors and pump!

I'm not too worried about the wiring. I use 10 awg for most of the run, and then step down to 12 awg.

I have been thinking about making a nice sending unit, but man there really isn't that much room.

Also, if I do a -8 feed line, I guess I need to swage the tube down to the 3/8" outlet of the walbro.

I got some ID1700x, and didn't do anything to my feed line. Required duty has dropped a ton; it's now hovering between 50-60% at ~30 psi of boost. They idle great on e65. I'll be curious to see how they do with pump gas on the way to Davis. So if anyone wants some ID1300s talk to me because I'll likely sell mine soon.

After installing the injectors and messing with the tune a bit, I went out with some buddies and did some pulls. My buddy who trapped 131 in the quarter can't pull away from me. My car is finally starting to feel fast.

Great to see the progress on this, and that's awesome that you're coming to Davis this year. Will be good to finally meet up and check it out!

Awesome news indeed man! FYI, bring your tuning stuff, we DO have quite a few E85 stations in town. I'm back to straight E85 now and we seem to be getting a decent blend in the Propel tanks right now.

I drive pretty slowly normally, I mostly like to go fast just doing pulls with people. I'll definitely bring my laptop. I already know I'll have to knock out a ton of wastegate duty. It loves to hit boost cut down there.

Lol. I'll raise boost cut when I don't have to drive the car 700 miles home.

I think I know what the problem is. Your titanium aluminide turbine wheel is too light.

It's been a while, but I've just been driving the car. I finally decided to upgrade the brakes from the RX7 and stock rear calipers I had to match the power I'm making. I don't think I'll ever put big sidewall slicks on the back, so holding out to fit 15" wheels in the back isn't a priority anymore. It's not a drag car. It's a street car and most of my driving is highway pulls anyway, so I put R brakes on front and rear. Maybe not the best option, but I got them for cheap and it's an easy job. I use a mustang master cylinder with a volvo reservoir and I shortened a wilwood push rod spacer to make up the difference.

The only tricky part for me was that my local hose shop couldn't find the same bulkhead fittings as stock for the rear soft lines. So I changed it from a bubble to a double flare and used these fittings:





Simple enough fix and it works just as well. Fronts look like this:





Rears look like this:





I also finally rounded out my Stack gauge collection and got a new boost gauge:
