lol... your right. im a newb.

except for my certification in: GTAW, FCAW, SMAW, GMAW, Oxy-acet., ect. ect. in stainless, various carbon steels, aluminum... in ALL positions and unlimited thickness.

Im no garage welder. I know what im doing. And if you want to go ask 30-40 year veterans what they weld with. Or just drop by a job site and see what they are using. Red or Blue...

You see, this thread is why I don't fab my own stuff... I have enough heart burn as it is

Geez, I make a two-sentence comment just complimenting the OP and this turns into a another 'show me the numbers' match. I would like to see some numbers as well but sometimes, it's just not a priority so too bad for the rest of us. I just thought it was neat; rarely does anybody do anything with the stock IC.

I will fabricate my own stuff if it doesn't include welding. If something needs to be welded, I know a good guy that always does our custom lab equipment. And yes, he's good with aluminium.

We did a project car that used two stock IC cores.

Haltech datalogs show it was within 3 degree F of a full GReddy FMIC kit for the FC3S.

Is that what you want?

That wasn't exactly what I had in mind, Ted- although that itself is also interesting. I was more or less referring to the fact that there aren't many TMIC modifications (not including the AI systems) that build upon the existing system. IMO, it always seems too easy to just slap an FMIC on and call it a day.

It's just nice to see somebody think and do outside of the box.

Cheers, everyone.

... sucess is mine. =P

I know that this dyno proves absolutely nothing since there is no before and after. But the power band and numbers are better than i have ever seen for whats done to the car. up until the bad dip in power at around 5500rpm, wich will be resolved very soon. I will be going back to the dyno in hopes of 250whp with the problem fixed...

sen2two · 03-30-2010, 10:50 AM

run 1: 3rd gear

run 2 : 4th gear (the 226 whp run)

RotorDad · 03-31-2010, 05:18 PM

Hey man I commend you on upgrading the stock TMIC, the work looks clean IMO. For some reason it seems that people feel the need to make things difficult. It's funny to me how this was a thread just showing one mans effort in making something better to what brand welder is better. Honestly most of the guys I know use Lincoln a few use Miller & a couple use Hobart or ESAB. My brother who has done deep sea welding & welding at prefab concrete company prefers the Lincoln.

Max777 · 04-01-2010, 12:13 PM

So, what's the dip from? It looks like the run with the most peak power has the most significant dip, even lower than stock. What was the AFR ratio? Was this a problem of HP, or is it a fuel/timing issue? Is your ECU stock or standalone?

sen2two · 04-01-2010, 02:16 PM

Stock ECU, turbo, motor, ect... The dip in power is from boost dropping from 11psi to 6psi due to stock turbo and wastegate no being able to hold 11psi all the way to 7k rpm. The 226whp run has the most significant dip due to being in 4th gear. The boost went from 14psi down to 6psi.

But i have an upgraded Garrett internal wastegate on the way to hopefully remedy this problem.

Max777 · 04-01-2010, 11:05 PM

Ok, a boost drop makes sense. Would installing a boost controller fix the problem? A garret wastegate, depending on price, doesn't sound like a bad idea.

11PSI? I have a 255lph pump, 750cc secondaries, and an RTEK 1.7 ecu... can I run 11psi then? My gague only goes up to like 6~8psi max right now.

A boost controller would make absolutely no difference at all. And given your upgrades surpass mine, you should be able to handle 11psi just fine. But to be safe, check it with a wideband to make sure your not leaning out or get some minor tuning done. an safc2 would be fine in your case...

Really? I thought that it holds the boost from opening the wastegate untill pressure reaches 11psi, therefore boost should not drop as much?

Or am i missing something here?

Have you tried using one to see what happens?
