Anyone ever try running a restrictor to keep HP down? I've thought that this might be a way to get really good tq numbers.

 

We were just there!

Looking at the results, looks like Ryan qualified with a 2:30.0. Best race lap was a 2:29.5. The guy that won ST2 was an Exige with a best of 2:24.7

Running a class lower - and in TT - I ran a best of 2:29.2. My required weight in TTA is 3263 and at best I'm 9:1. The car that won my class was a 'Spec C5Z' with a 2:26.3 on stickered A6's and I'm sure right on 8.7:1.


I dunno about Ryan, but it was my first time there. So I know I can improve, but I'm not seeing 3 seconds on my current setup! I need more hp for sure...
I think we all agreed that we'd need a completely different setup for Road America with more HP. Are cars aren't geared well for it either, it's hard to pick up much acceleration past 140mph (especially uphill) running 8.7:1 modified...

 

I've been pondering that myself but it'd require shifting a lot more because it moves the whole powerband back. Some of the big block guys on the nasa boards were even crying that "boosted cars" need a restrictor, and I started laughing .

 

Alright guys.... should I cage it?

 

Yup!

 

Depends bro. I personally miss my car in street form, however my goal was to race, not go get groceries. And you've already got the truck/trailer.

 

It's been out of street form for awhile. I could drive it, but with all the stickers, loud exhaust, rollbar, stripped interior - and usually on race rubber and brakes... Rarely.

 

Good question; I like how Ryan's (hamflex) car is set up with the 3-port boost controller that keeps his HP consistent and allows for a lot of torque. The issue is that it takes time to dial in therefore requires dyno time and a good tuner (which we don't really have in Pitt)

So you could drag it to AMS or maybe CBRD (if they tune for it) but if it needs adjustment then you are kind of SOL until you can get back on a dyno?

Would the restrictor be easier/simpler to tune? If so a few pulls at J&S; send the logs to John and see what he comes back with

 

No; not until you know for 100% sure you want to race w-2-w next year. Plenty of time to think about it over the winter

 

I wanna race something! And caging my car is cheaper than renting (damn, renting is expensive).
Yeah, there is time to think about it. But the good builders fill up their winter schedules pretty quick - which is the situation I'm in now. Deposit time if I wanna do it...

 

My two cents...

The only real "negative" with caging your car would be shrinking the size of your potential buyer pool if you decide to ultimately sell your car. On the flip side of the coin, anyone interested in buying your car now is not likely to be turned off because of a welded cage. With that said, do it...

 

That's kinda what I was thinking too.

I mean it is registered still, and technically streetable. But with race suspension, race alignment, a race seat, a rollbar, stripped interior, no horn, no airbags, 6-pt belts (no 3pts).... How 'legal' is it!

Caging it - even if I don't race it - should expand the potential buyer market down the road. Plus it'll make it safer. The little guy does 144mph+ at Road America, Mid Ohio and VIR already...

 

i look at it this way.... if you were to sell it, would you be selling it as a race car? or put it as much back to streetable as possible and sell as a general "modded" evo. if your selling it completely as is, having a cage wont hurt the sale to whatever potential buyer you may have. selling it as a street car will make it impossible to sell to your general populous.

putting the cage in my evo made the car MUCH stiffer. it was immediately noticable, and made the car feel much more planted. i also felt much safer

also, when doing the cage, its very easy to take a lot of weight out of the car. for example, last one we did, the car came out about 150lbs under weight for TTC evo 8. and we didn't event try to gut the thing at all. thats including the weight of the cage, it weighed 2960lbs.

heres the entire build with the detailed cage construction

we typically only tune with ecu boost

on the 9's we do alot of tephra maps with gear dependant boost

Sounds like a good and reliable solution.
