FP Red on MS109

 

Oh and there is no E85 where he is coming from and doubt he'll be using race gas,if he is, he'll be using avgas.

 

I hear what you are saying, 4G63W8, about gearchange transient response. And I also agree that a standard journal bearing Red/10.5 may be able to deliver the peak power, but it may be lacking in transient response right after shifting.

I wasn't too happy with my Green/10.5 in the transient response department, so I had to go down to a 9.0 turbine housing. Part of it has to do with whether or not he'll be running an JDM RS close-ratio box, which only drops the engine revs down 200 RPM after upshifting. The turbo needs to be right there instantly , especially with ALS and close ratio gears.

 

I used to run a green with the 10.5 hotside,externally wastegated though,it unfortunately broke,so I now run a stock 9 turbo,you are right about the transient response in relation to the rs gear box,that's probably what he'll be running,jugding from the way they do things down there as I know the island and people really well.

What I've noticed on my jdm evo 8, 6speed gsr box,is that when i had the hks 272on 0 the transient respone was better than what is is now,minor difference though,but the 9 turbo used to surge badly as i run the fp 18psi actuator,of course i had too much proload on it,spooling was fantastic though lol,so i set preload on 1.3bar in 4th with the settings on the profec on 0, and now with the new dialing of cam gears,i have no surge just a bit of flappering on 4th from low revs and the top end has improved running 1.75-18bar steady to redline with the help of the profec b.

I'm thinking of changing to a bbk Full with ported option using the fp actuator on it and was wondering if it would be worth it,any comments Sparky?

 

The top two liter turbocharged hillclimb cars in the world use much larger turbochargers than a red or green.

Andreas Gabat Cosworth 700 whp
Alexander Strobl- Cosworth 608 whp
Felix Palier- Lancia Evo 645 whp
Toni Bueler Evo VI -600 whp (AMS GT35R)

Those are serious cars of course. We don't really have any idea at the moment what type of budget accompanies this build.

 

Any idea what setups the other guys on your list are running? I'm just curious how our build is going to stack up against these Euro-beasts.

Also, not sure if you might happen to know, but what sort of setups are the 'rallycross' cars from across the pond using? Rumor is Gronholm may be bringing a Fiesta to PPIHC this year.

Thanks!

The OP mentioned fast spool and lots of torque and a power peak of 550. I realize that the Green won't get him close to 550. I just mentioned it because it spools relatively faster than a Red, although to me it didn't seem to spoolup quick enough with the standard 10.5 housing. I was only making a comparison.

On race gas, the FP Red can get an Evo to the OP's 550 target easily enough(even on the stock ECU)and it'll spoolup a whole lot quicker than the AMS 35R kit. For a 550 WHP Hill car I'd rather run a Red with a Ball Bearing cartridge and a 4" Turbo Dynamics inlet cover.

 

DaveK: What turbo will you be running on your Pike's Peak car next season?

 

Honestly not too sure yet. My orig. thought was to start with a 30r for our local hillclimbs (tight & twisty), then maybe using a 35r for PPIHC. Even the 30r is going to be quite a step up, so who knows if I'll want more....ahh, who am I kidding, if you can't leave black marks the entire way thru Picnic Grounds, its not enough.

You're the Man!

 

the car is cruise power evo 7 stroked to 2157cc. the car was a for track use but we bought it from cruise power and brought it to cyprus. the strange thing was that the car had everything (stroker, injectors, lsd, advan rims, fcon, etc) except turbo. it was the standard evo 7 turbo.
i am living in cyprus and getting parts from overseas is a PITA.
we were thinking that the gt35r would be a good choice cause most of the hillclimb races have 2-3 long straights and with the stroker it might not be as laggy.
we were also thinking for the t67 25g and water/methanol injection.
the duration of the hillclimb is about 2 minutes.

 

hks GT2835 is a gd choice too
they spool incredibly fast

 

Dave, I'll try to find out. I watched this long interview last night with Andreas Gabat to try and learn Gabat uses a Group A Garrett turbo with no restrictor. I'm not sure what the Lancia's use although I have pictures if you want me to email them to you. You can see a lot of those cars on you tube.

My car isn't at their level yet but I use a PTE journal bearing turbo with mild ALS (need to get it working better) and my car makes 490whp on our dyno dynamics. Courses in New England are tight and twisty and I think that the spool is acceptable.

I would kill to go to PP! Maybe in 2011 I'll see you there.

 

This is Felix Palier's Lancia. Sorry, no turbo **** shots.



What I was mentioning about the power and the OP ect is that his car will probably come up short on expected power. Don't they always? So maybe shooting for 600 will yeild him the power he wants/expects.

For example I've never seen a green or red dyno graph from a Dyno Dynamics that reads over 500 but on other dynos it's been done.

 

Finally some good info pertinent to the topic. You need to match the motor, turbo, and cams to RPMs and the application. Picking one of these and thinking it will be the best set up is a mistake. The Turbo is only a part the the equation.
