Hello everyone. Right now I have a Vargas GC on my 340 with spool fx180 pump as the only fueling upgrade, no port, no meth. I was thinking of upgrading my turbo but I'm really hesitant on spending $5k-$6k on a big turbo kit such as Bigboost or Doc race.

I also want to stick with factory EWG which basically eliminates big boost but to my main question- Will I see any benefit from upgrading to DAW turbo from my Vargas GC with my current fueling? I do not plan on doing port injection yet either. Would appreciate any input, thanks!

I recommend you check with your custom tuner on what kind of power they can safely generate with either option.
Then you can decide if it's worth spending money on the new kit.

Good point thank you

EFR8474>GC at the same 25psi boost and E30 fuel, at 50-75HP.

BigBoost has an EFR bottom mount kit that will reuse factory EWG, but it's still $5k+.

And your Fx180 has a lot of headroom for fueling left. According to the stats, it flows more than Dorch stage 2.

Yes I just saw that now. Surprisingly enough I ran into hpfp rail drops a few times with my fx180 and GC turbo kit during revisions, didn't think that would happen with a GC

Who's your tuner? Lol that shouldn't happen.

What about the EFR9174? My goal is to make atleast 700whp under 30psi boost with just Dorch Stage 2 hpfp for fueling. It'll only be worth paying 5k+then.

My hpfp is holding strong with the GC.

Won't mention tuners name because I don't want it to sound like I'm talking bad about him lol but he's a very reputable tuner

Lol well it's in your signature. At least it was during revisions, but your final tune was smooth, correct? That's all that matters. But still surprised to see rail pressure drop on E30 with GC and FX180. That midrange must be nasty fast lol.

Oh no I was on e50 that's why lol not e30. Yes fueling is smooth, just dealing with timing corrections on and off

8474 best for stock engine. Boost comes from 3200rpm. Full boost is already at 3850rpm.
The 9174 blows later and the power comes on more abruptly. Check with the seller of these turbines. He has a lot of information. In any case, without PI and WMI, you will be limited to 3500-4800rpm on the E50.

This car made 650whp with 28psi boost and 10* timing. And it's awd. So maybe were looking at high 600s with the 8474 on more timing?

I have more power on GC))) This is such a setting.

Thanks, this is exactly what I was looking for. I want to limit the torque to 550-600ftlb and it looks like the EFR9174 makes 600 at 3500rpms.

How's the spool on the 8374?

I know it will limit to ~650HP but I'm more concered with WHEN the torque and HP occur.

I'm not that excited about a set-up that effectively limits the power band to 4000-7000 rpm.

I'd get a DAW and call it a day who says you can't tune your car for consistent hp/tq throughout the entire powerband compared to peak hp/tq?



Tuned by sameh yehia + his post description:

"thought i would share this for those who wonders about DAW 2.5 numbers.
i had a car with me yesterday on E55(port injection with OEM LPFP),its a daily car and my customer didn't want to stress it, but i liked the power band for mid low 600 whp daily car
it probably had bit more and i didn't want to stress it at all
peak power @ 27.4 psi ,i have noticed the increment in power compared to the boost started dropping at these boost levels and WGDC started to work harder up top, so probably at best fuel blend the turbo will be happy at around 29-30 psi and still have solid power band."
