I plan on getting a few more things and then hitting the dyno. there really isn't much info out there, but i would like to take a stab at "bastard dsm's" record for the 18g.... i have tried to contact him several times with no reply. my car feels like it is no where near his 455whp mark that he set and i was wondering what direction to go to help my chances. thanks for the advice in advance

So you are going for some kind of record, and you want that record holder to tell you how to beat his record? That makes perfect sense; I can't believe he hasn't replied to you yet.

based on the stupid link calculations the car is making right around 400 hp right now. i just wanted to know how "bastard dsm" made so much and what little differences his setup has.


all and all there is very little solid info on the 18g out there compared to every other "dsm turbo". but I am very happy with how the car feels and pulls. i managed a 12.4 @ 114mph in the 1/4 with a 1-2 shift you coulda made a sandwich waiting for.

Those times & MPH are NOT proving 400awhp. You've got some tuning to do to hit 400.

we are all here to help each other out LOL what do you think i want some kind of trophy or something for a 18g record? LOL and yes i agree i believe i am not @ 400 hp mark yet. although i did trap more than you and your over 400whp. those times were before cams and with a blown head gasket LOL

No offense intended, I was just trying to show you that it makes no sense to ask someone to help you break their record and be surprised when they don't respond, maybe others don't share the same opinion on that as I do. I don't know how or what you actually asked him though, so I guess that matters most.

It looks to me that you have the parts you need and then some for 400hp, > 450 I don't know. Post up a log, then maybe people can actually help. It's all in the tune.


the dyno was on 5spd, times on auto. Autos are geared crappy for 1/4 with my setup (but great for 1/8) and autos take more power away.
 
you can see my track video on the quarter mile challenge. LOL my tranny wasn't the greatest so my 1-2 shift looks like you can make a sandwich in the mean time. i'll post a log. i just put the head on last night with the cams i'll be doing a bit of tuning this weekend. i'll most likely get a smim in the then hit the dyno to see what i can make while i save up for a bigger setup. i would really like to spray the car maybe even with a just a 50 shot or so but idk if I have enough fuel to run a dry shot then add fuel through the injectors with link.

ROFL

No sarcasm intended. :D


Really, John is right. I know for a fact that the power I lack is because of my amatuer tune and an intake that is a bit constrictive for the amount of air the 18g moves. The more I get the tune dialed in and the parts I have now working properly, the turbo makes big jumps in power. The potential is there, but it needs to be dialed in, and since it isn't a common choice of DSM turbo, you don't get any people showing tunes you can model after.
 
a little update. built and ported head is on. i let the car idle for 15 mins or so, no leaks and ran good. im gonna drive it around the neighborhood for a couple mins then re tq the head. we'll see what kind of power it makes in a couple weeks and then go from there and see if it's worth upgrading anymore on this turbo, or just start planning and collecting parts for whatever i get next.
 
Ever get anywhere on this? I had to put my FP18g back on a couple weeks ago when my HX40 snapped its shaft.

I plan to stick with the 18G now that my setup is better then it was back when I had it on before and see what it can do.
 
I wouldn't be so concerned with dyno numbers when they vary so much between different dynos such as mustang to dynojet for example, let alone differences from place to place that even use the same kind of dyno. They are most beneficial as a tuning tool.
 
Still haven't dynod, I'm switching to a 7 bolt head and smim
