How many of those guys are running cog setups? Also how much boost are they pushing out of their blowers?

 

Damn John, you're starting to sound like a Vortech salesman. I'd gladly take an F-1R over a YSi if I ever ran a belt-driven setup again. Maybe I'm just crazy like that.

 

Within a year he is a blower expert.

 

When is your car going to be ready?

 

Mong, that's a fair response but try this. Step back, and pretend you are a shop. How will you go about selecting a blower head unit for a new customer. Let's say you want to select a head unit based on the results that folks have had in the say last five years. If that's the case why would you select an F1?

I've given the Vortech YS/YSi examples.

Now, would I do an F1R? If I was building a motor that buzzed 8500 rpms like Ronnie Duke's I might consider it but I would also look into the Vortech X and XX Trim blower of which I know nothing about. I just know the F1R needs rpms that my 7200 red limit hydraulic LS6 motor can't handle.

I went thru this exact same process a year ago this month... what blower head unit to get. I found 10 examples of why to get a YS, and one example of why to get an F1R. And no examples supporting the F1.

And of those examples I think most of them were cogged in the end. But I can give 6-7 additional examples of Renegade NMRA Mustangs running 8.89-9.20 with an YS/YSi 8 rib setup at 3300 raceweight in addition to the LT1 examples I gave.

 

Sorry to burst your bubble but the F1 has not been out for 5 years. You are comparing a blower the (YS-Trim) that has been out for a while and an F1 which has been out for 2 years (if that).

 

Renegade friend said YS has been out for 3 years, and F1 for two. Again I have nothing against you Idox, just find me cars that run the number.

 

we have a F1R on a 87 Formula. it's a 406,doesnt go above 7300rpm. we chose the F1R over the YS for a few reason's,some of them included the YS wouldnt make the target power goals without overspinning the hell out of it (and yes NMRA cars spin the YS to extreme's,and they come apart). And the YS didnt flow enough air for our goals.

the F1r has wroked great,we have much less belt issues then with the old T trim,both setup's are cog. This is partially due to ATI's better internal stepup ratio allowing a larger blower pulley for more belt wrap.

It is a street car,passes inspection blah blah,will run around on 93 all day.
It has performed well,best to date is 9.27@151 with a spinning 1.46 60',it now has a transbrake and different gears outback.Car weight is 3570ish w/driver.

 

Is that Tory Hess' car?

Sounds great but let's also note that it's a 406ci Dart? not an LT1.

 

I have nothing against you either. You are right the YS trim is alot more popular and people are having great results with that blower. Unfortunately I am not a big dog so I am not a good representation of a person running an F1 to it's potential. RsKrause is making great power out of his blower and is running 10 teens. He is also running a full weight car (over 4000 lbs).

 

I thought rich krause sprayed the car to the 10.1 pass. didn't he say he hit it with a 75 shot?

 

yes it is Hess's car,should go 8's this year.

as far as the LT1 and F1r,it's something i have been considering doing......just need to see how much it's gonna take to get it to fit.

 

Yes, but I don't think my car's track performance says much about the potential of the F1. My car+driver does weigh 4,100lbs and it is kind of a "bastard". Full street equipment including cats, AC, etc. and a "road race" type suspension. So, it only runs a 1.6 sec 60'. Last year I was running a fairly small HR cam and unported AFR 195's (260CFM at 0.600"). The non N2O passes are in the 10.7 sec/136mph range. In case anyone cares, I had some head work done this year (now 285CFM @ 0.600") and will be running a bigger cam. We'll see how it runs. But you can't compare my car to the 9 sec. Vortech cars that are out there. The are pretty much "race cars" as far as I can tell. FWIW, my buddy has a 331ci stroker 5.0 and an F1R. He hasn't got it fully sorted out yet, but runs low 9's and has ~800rwhp with a small cam, full exhaust, etc.

I definitely don't want to get in a Vortech v. ATI pissing match. As far as I can tell there isn't a lot to choose between them. I have no emotional attachement to my blower at all! Too bad we can't get compressor maps from P'charger. They say that once their lawsuit with Vortech is resolved they will release them.

Hi Rich, I am just keeping the content accurate, you have a total street car and the examples I have been referencing are mostly race cars.

 

Have you ever installed a YS-Trim on an LT1? If so I need some help. My buddy is putting one on his car and he is having issues clocking the blower so the discharge tube is facing vertical.
