Upgrading to 19Ts

[DocWalt]

If you use all of the failsafes on a modern meth system you'll be fine. Good to see more 19T builds

Thanks, there are a bunch of us bolting on 19Ts at the moment it seems...

There really is. It will be interesting once all of us start wrapping them up and putting out numbers.

Using meth is still intercooling, just by means of chemical induction. There's nothing wrong with this approach, if done properly.

My car at the shop getting re-dyno'd - 3000GT/Stealth International Message Center

i had the dyno L-HL comparisons but i must have deleted the pics in my photobucket. Matt has some comments from when they were up there so you can see from there. I made 551awhp and 640 trq on E85 on my 19T-HL's.

looks like you picked up a average of 30hp from 4300rpm-up at the exact same boost.

That's a good comparison right there. You boost is nearly identical.

So with HL wheels, stiffer wgs, 6lbs of more boost, an amplified ignition system and a more agressive tune you made appx. 60 more whp? Peak HP..that is...got any dyno charts? Would love to compare old and new dyno charts..

Hmm...to sum it up, to date the fastest 19T cars are:

Dale's 19T car--which was kinda over the top, not your average typical 19T car

oohnoo's VR-4..what did he make...550whp?
kywhitelightning..he has a VR-4 that made 59Xwhp with stock bottom and ported heads
Sin's VR-4..551whp..

6 more pounds, is about spot on the norm 10whp per pound.

sry i am refrencing a thread from the other site but has alot of stuff in there. I am currently running WG only at 20psi. The pic shows max trq 641, max awhp 551 and psi 26.1. Trying to see why with my BC and wg lines on, im maxing around 23psi, but with wg's only im at 20psi. hmmm.


sry, just piggybacking from the other site you posted. And i dont know why u wouldnt just go with HL wheels instead of the L's?

Denso pump uses 50% more current doesn't it? Will you hot wire it or do the RDR rewire with a second resistor in parallel for the low flow mode? You're replacing the MBC with the LCDBC - may need to replace the stock solenoid to turn up the boost. Also, don't you need a MAP sensor to work with the 99 ECU?

You're replacing the MBC with the LCDBC - may need to replace the stock solenoid to turn up the boost.

Indeed, Jim - with one of these, per Antero's recommendation-

-or the AEM solenoid, if you really want to overspend.

Go for the mac one j2k4 posted up, it is a great unit.

No you don't need a MAP sensor. Everything is done off airflow.

You need a map sensor if you wish to log manifold pressure and convert the stock boost gauge to be accurate but that's it.

I've eliminated psi based boost control from Chrome V2. There are many reasons for this but its off topic from this thread.

Just confirmed a couple weeks ago that using the stock FPR solenoid as a BCS works great too!
