unfortunetly not yet, tuner just said it coldnt hold 1.5bar past 5k. Car is going back beggining of next week for retune with hd actuator so i will ask fo a boost map then.

How does the dyno graph look like for others with the FP Green? Do you guys get strong top end? As i seem to struggle with top end with this turbo.

 

Here is my dyno chart @ 32lbs tapering to 20lbs on 111oct...the taper is the nature of a small turbo...it just cant keep up with the demand...

FYI: This was WITHOUT the 18lbs actuator though...

Keep us posted on your results with the new actuator if you go that route...

 

I wonder if Bryan (Razorlab) has that kind of boost taper with the GM 3-port solenoid.

 

If I revved to 8000 rpm I probably would. Why you would want to rev to 8,000 rpm with a FPgreen I have no idea.

 

alan, you need to do a C-16 tune bro. I bet you be in the 450-460whp.

 

Because FP said i could, and i have the cams and lifters to support it...

'The 69mm 5blade CNC machined compressor wheel has a flow rating of 47lb/min and pressure ratio capability beyond 3.7:1 which allows for over 30psi boost pressure and RPM range beyond 8krpm.'

Details aside....this is us here....the testers and the tuners...showing the facts...

Mind sharing your boost plot?

Here is my boost at 7k since we all don't rev to 8k

 

I don't see the advantage to revving to 8,000 rpm from your dyno plot unless you are on the track and need the extra gearing for less shifting and faster lap times. You lose more than 50whp from 7k to 8k, but to each their own.



Sure, here is my current boost, I've had it hold 24-25psi but it seems my car gets a little grumpy on 100 octane with more than 24psi being held.

 

alan678: What rpm is your boost peaking at? before its starts dropping.

Has anyone got a dyno graph of a fp green on pump gas? and at what psi?

 

Does anyone also know if a Tial 38mm external wastegate will fit on a FP Green? does anyone know also what kind of gains this would give compared to the std unit.

 

It's an internally gated turbo. I know David Buschur did some testing of external wastegates with mediocre results. Doesn't mean it can't work, but I think you're creating more hassle than it's worth.

What happened with the HD actuator?

I find it hard to believe that .2 liters displacement makes the Green run out of air so quickly, but perhaps a 50trim is what you're looking for?

You could also try contacting Jestr. He does ECU tuning long distance. He sends you a base tune, and then you send him your logs. THen he sends back adjustments and so forth until the tune is spot on.

 

Car is at the mechanics as you read this...so will have results for Hp Actuator within 48 hours....

But I was just researching and viewing everyones dyno graphs and it seems consitant that all FP Greens have a steep curve to about 5500rpm and then sort of flatten out.

Which makes me think that the results of the HP actuator wont do much. Just seems like you guys get allot more power since you are running much higher boost levels on race gas etc.

Ill know soon the results for the FP green but it looks more likely that the GT35R would be a better turbo to run on pump gas.

Ill keep you guys informed.

 

Honestly, I think the BB50 trim would be a much better pump gas turbo than the 35.



Are you tuned using ECU flash?

 

BB50 trim? I assume this is a ball bearing 50 trim turbo? What turbo is this exactly? and why do you say that? I need some turbo education!

My goals are basically to have a turbo that will make about 400-450hp on 20-22psi on pump gas with the fastest spool possible.

will the BB50 trim make 400whp on pump gas and 20psi as oppose to the GT35R or GT3076R?

 

I offered to look at AMI's tune, no response

 

Its going to depend on what gas you have where your at and what dyno. On CA 91oct and a number of bayarea mustang dyno's you wont be able to see more then low to possibly mid 300's, even race gas would be unlikely to hit 400.

Your looking at the whole thing wrong. Instead of shooting for peak numbers, you need to figure out what you want to do with the car. If you do get 450hp on pump gas, chances are you will loose to a car with 300hp unless you race them to 160mph. On top of that if you plan to track your car ever it will be useless with a gt30 or 35 without basicly a complete race setup and then you would have to know how to drive it.

You can make a gt30 streetable but if your running it on pump your really not using the turbo in a rang where its efficient, and would most likely get walked on by a well tuned fpgreen or 50trim. Peak numbers sound cool when you bench race, but peak numbers dont make a car fast. for instance, my old viii had about 265hp with a pretty nice curve and i would walk away from a local guys ix that had some bolt on's and a off the shelf map. He made 294hp but only for a split second and the curve looked like crap. So he made 30 more hp in a car that is suppose to be more efficient and still got pulled on well into 5th gear by a old viii with a 9.8hotside and no cams.
