Its definitely attainable

 

i really wanna order the 20g9-5 from buschur im jes not educated enough on it yet and there is soo much bs in the forums about it...i really wanna make about 420whp or so on pump plus meth...

 

Your TQ looks relatively weak for the mods specially your race gas numbers.

How much Boost are you pushing?

 

i know it is weak i could never figure it out, on pump 22 psi, race about 26-27...

 

you should be in the 380 wtq range

 

I will be tuning a "like" setup this week, go see my thread for updates!!

 

alright cool thanks...anymore input is greatly appreciated..

 

400+ is easily attanable on race gas with the 20g and your mods. i have one and i love it.

 

FWIW with a 3076R and a 2.3 I am making 20 more hp than you and 35 more ft lbs of tq then your race tune on pump gas and 20 psi.(I can see you don't want lag, I make 22psi at around 3900 rpms.

If you go with a 3076R or some variation of it over a 20g, I believe your race gas numbers will be much much higher, while the pump numbers will be similar to a 50 trim/20g.

Ian, I think you would be really happy with our 50trim or 30R kit. It was nice talking to you the other day. let me know if there are any other questions, Ryan

 

Hate to tell you man, but you're gonna need a GT3076 or larger to hit 400whp with meth or alki, and you'll still have a difficult time doing it. The 20G isn't going to come close on a respectable dyno. I can't speak for any of the lunar dyna-packs or dynojets in the LA area, but any loading dyno such as Dynamics or Harmans isn't going to get you close. The 20G will do maybe 340whp on alki/methanol at best which is about 20whp more than the stock turbo with a 10.5 hotside.

You can compare this to the Bozz EVO running the HKS GT3037 (pretty similar to GT3076) tuned to the ragged edge on C16 (HKS F-con Vpro). They did ~415whp on our dyno, and ran an 11.2 at the track.

Keep in mind that 400whp is well over 500HP at the crank and there are very few modified 4cyl cars are able to hit these numbers and still drive on teh street.

keep em coming

 

does anyone have a flow chart i could look at of the 20g-9 and the 50 trim as well

 

Quite a few persons here have achieved (including myself). Of course, this is strictly speaking Dynojet numbers, which seem to be regarded as a de facto standard of sorts.


FWIW, I generated 348whp on a Dyno Dynamics using a regular EVO 8 TME and 93 oct + methanol.


FYI: That estimation is somewhat inflated, even where Dyno Dynamics whp numbers are concerned (discussed ad nauseum in another thread).

 

Hi Ted,

Thanks for your response. Honestly I really don't like quoting dyno jet numbers not just because of the fact that we have a mustangdyne or the majority of dyno-jets are non-loading but more so because there seems to be such a huge variation of dynojet calibrations, where as the mustang and the DD seem to fall in a tighter group. There have been cars that we have tuned that pull on straight-aways on other cars with over 100whp more (on paper, dyno jet). Furthermore based on the MPH trapspeeds, I personally take all dynojet numbers with a grain of salt. I guess that's just me though.

348whp on a DD is an awesome number! The best we've been able to push is about 328whp on our Mustangdyne with the stock turbo and alki.

As for the 500 crank HP number I think a ~25% drivetrain loss for the EVO and Subaru is fairly inline. We've had some cars that have engines tested on engine dynos pre-installation and have come within a few percentages of the 25% drivetrain loss in the 400-500whp range. That and we did have a factory rated 500HP Viper GTS make 386whp here.

But I agree with you, every dyno is different so it's really hard to quote "power" based on different dynos.
