We were able to actually mount the turbo's further away from the Trans compared to how we received it. This caused a problem with air flow, as now the Turbos were too close to the frame rails. The solution to that was to....this might sound weird and it's hard to explain w/o pictures.....the solution was to redesign the Frame rail and essentially turn the frame rail into a boxed air Plenum. It sounds funky, but when you see it, it's really freaking neat.

Now if you're running auto-cross they're a necessity, but what's the general consensus you've seen on how happy people tend to be with those when they're just building a roadster?

If your concern, KC, is that the Turbo's will get too hot, i wouldn't worry about it. Where they're located is completely open air. It's very similar to a Squire's STS rear mounted design.
Our main issue was making sure that they didn't make the cabin uncomfortably hot. The Turbos will be wrapped in Heat Shield as well. Twin Turbo 5.0 Coyo Mod motor in a 2700lb car....this thing is going to be a kick in the nuts, even if we turn the boost down, which we most likely will. We'll turn up the boost for the Dyno when the the time comes just so the customer can have a Big Dick dyno sheet, then we'll likely turn the boost down to around 7lbs so it's a more practical driver.

I was referring to the boosted air temps (heat soak) though. Where's the intercooler going to be placed? |

Here's a few issue we have with it: 1. The Rear suspension control arms drop way too low, forcing the customer to have to run a minimum 18" wheel, otherwise it wont clear the arm. Secondly, the track width pushes the wheel out further than stock (a big no-no on a car with an already limited wheel house). 2. The front suspension uses those Corvette Spindles....which are freaking huge. Same problem as the 1st, forced to run a large wheel, and again pushes the wheel base out, on top of being heavy. 3. The freaking spindles, being from a Vette, still had the stupid GM bolt pattern, meaning we had to redrill and stud the Spindle for the appropriate pattern. Otherwise, the customer woulda had a Ford bolt pattern on the rear and a GM pattern on the front. Stupidest thing ever. If we had our choice, that suspension wouldn't be on the car.

We're not sure that that'll suffice though. Haven't gotten that far in the project to worry about it yet.

As far as how it drives, DJ, i don't know. Like i said, we would never put our customers into that suspension if given the choice because of its inherent issues. It really is a beastly suspension that doesn't fit the car as well as other suspensions do. The thing is, we get these high roller customers who just go shopping for the most expensive, impressive looking stuff they can find....but that doesn't mean it's the BEST stuff.
Hell, we retro-fitted the front suspension off a 3-series BMW and put it into a '66 and it was less hassle than that shit is. No joke. I'd put the Global West stuff in there before that stuff, and Global West isn't even our favorite.

We built a a Twin Centrifugal supercharged 392 with twin intercoolers that ran into twin Viper throttle bodies top mounted, above the Valve Covers.....people said it couldn't be done and was ineffecient....never once had an issue with it and it was making around 900hp at the wheels on less than 10lbs of boost. Also, sometimes design trumps functionality in cars like these. Gotta remember, these cars belong to 60-70 year old men who are gonna take it out once in a blue moon and show it off. Our main concern is that it can be driven comfortably, so these cars will be de-tuned. These cars will never see a race track.

Like I said, it seems like the Autocross guys swear by the stuff because as you noted - it's heavy duty stuff. You could drive the sucker hard into a corner without working about snapping a rod. And sure, weight matters in those races but when you're now working with 700+ HP, suddenly the trade-off of an extra 15-20 lbs for the added durability seems worthwhile. If I ever just fell into some money and felt like re-building the suspension, I think I'd probably just go Hotchkis all-around after doing some homework (I'd love to find someone that could do a Guldstrand 'round here but it's almost certainly unnecessary). I will say that you are as vehemently anti DSE as anyone I've seen, but they do some geared towards the hardest driving and I'm just not going that route with it.

Our favorite suspension is made by Gateway Performance Suspensions. It's light, uncomplicated and handles incredibly well. It's a McPherson Strut conversion for the front with a proprietary Power Rack and Pinion (not some rebuilt, remanufactured rack) and a triangulated 3-Link in the rear.

Don't worry, you'll love that car i made the naming thread for. That car is going to be all about functionality....it's going to be made to drive the piss out of it....non-forced induction though. All motor.
That's why we're really looking forward to that one. We rarely get to build cars like that.
