HX35 Galant First Trip to the strip.

[doesitonall4rs]

Hey Guys just got the Galant VR-4 together last week, decided to take a trip to the race track just to see where the car sits on 25Psi. I am limited to 25psi because the IDCs are at 92-93% AFRs are at 11.8-12.0 timing is at 21-22* (E85) degrees, base fuel pressure set to 45-46psi to try to have IDCs somewhat under control.

It was really tricky figuring out how to launch on 195 economy tires, Had to mess with the 2 step and try various settings in link to get a launch I was finally happy with.

Anyways here is the time slip(Time is on the right)/video/ and some pictures of the car.

Isn't the fastest car on here, not looking to break any records, but I am trying to keep this thing comfortable, full interior, full sleeper status. In a few weeks I am going to go back on 1450cc, walbro 400 and 30-33psi Hopefully can get the car into Mid 11s (which is my goal for it and then just have fun with the car)

Very nice, awesome sleeper!

 

[doesitonall4rs]

Thank you! Next to the E85 this might be my favorite mod on the car,

Nice run for a old heavy boat Well done!

 

[codeofdastreets]

1.7 60gt for a 195 tire... Not bad at all

 

[Pipnorcali]

Nice times , family car sleeper...did you fall asleep at the tree..hahah

 

[pyro719]

Good job man! Does that electric cutout provide much of a performance gain?

Lol! It was the last run for the day before the track closed, i was trying to nail the launch as good as i could!

Honestly besides going by the butt dyno, my only hard evidence is the data logs, with the dump open link estimates 470-490hp, with it closed it estimated 410-430. I wanted to make a pass with it closed but i was scared if the excessive back pressure would cause higher EGTs

 

[nfernotalon]

Yea good times for the big boat. My walbro 400 just crapped out a couple days ago im guessing it was the e85 , you might want to look out for that.

 

[dsmcurse]

very impressive to get that kinda power on a "crap-a-bishi" mass air flow sensor, good job man! nicely done!

 

[bastarddsm]

Yeah that 2g maf is holding you back bad. I picked up almost 100whp on my HY35 going to a maft from a hacked 2g maf.

Same boat over here. Once at COBB TUNING SURGLINE I only made 280hp, they told me "i woulda made more power on a smaller turbo, and that the mass air flow sensor cant keep up with the flow and its seriously sacraficing my tune"

I went home and swapped from a 2G maf to a 3.5" GM. That was my only change. Came back to the same dyno shop and made 370hp

mitsu maf = poopy

Hmm thats strange, how much miles did you put on your 400? I have had one on my 3000GT for over 1 year now on E85, still working like the day I bought it.

Hmm, So far I have ran an 11.2@125 shifting like a grandma in my 1G dsm, still using a 2G maf and mafclamp feature with a Omni 4bar sensor.

btw bastarddsm, hacking the 2G maf is a horrible idea, I used to have a hacked on when i switched to a good 2G maf it worked great felt like i picked up 80 wheel

With all that being said anybody know the record for a 2G mafed car?

 

[nfernotalon]

Id say about 7 months. It was working fine then one day the car died on me while doing some tuning i tried to turn on the pump thru link and didnt come on, I tapped the sending unit and it came on but it sounded horrible got me home then the pump wouldnt turn on at all. I had to put the stock one on. Who knows maybe something was wrong with it.

 

[bastarddsm]

I went 11.25 @130 on a hacked 2g maf, car weighs 3400. Hacked 2g maf only hurts drive-ability. It definitely helps flow, you can watch it pull the baro down to about 12psi in my case.

 

[doesitonall4rs]

By hacked do you mean all the honey combs gone? Or just a select few? On mine all the honey combs were gone.

I left the ones where the air sensor is. Then smoothed the step out everywhere else.

 

[doesitonall4rs]

Gotcha, Thats probably why mine sucked, it had 0 honey combs.

Anyways, little update guys, Installed the 1550CC injectors/walbro 400LPH. Car is at 30psi with 74% idcs AFRs in 11.8-11.9 range. Car feels great! Just waiting for the next test and tune! Hopefully I can reach my goal of mid 11s!

Car started breaking up at 6K with plug gap at .025 on the NGK BPR7ES and accel 8mm wires. I switch to Magnecor Wires off my talon and BPR8ES, seemed to fix everything, not sure if the plug is too cold tho.

 

[Boosted DSM 32]

Nice numbers! Your setup is almost identical to mine as well which makes me happy I plan on running around 25psi on pump gas and trying to dip the car into the 11s which i dont see being a problem with a good tune since my 1g is a good bit ligher than your gvr4!

Car looks good and runs good you should have a fun car there sir!!

 

[doesitonall4rs]

Went to the track today, since adding bigger injectors/bigger pump, Car is at 28psi, traction in 1st gear is starting to get really hard to find!

Got 5 passes in best 60 foot I got was a 1.760 and thats when it went 11.7@120 @28psi.
https://www.youtube.com/watch?v=DQuHiX38jCg

I upped the boost to 30-31psi managed to trap 122 but traction was almost non existent in 1st ended up running a 12.0. Might have to look into some thing to help me with getting some kind of traction in 1st gear as soon as boost comes on top of 1st it spins/wheel hops.

 

[Dsmkauai]

Use less boost in 1st till you get better traction, then up it till you feel comfortable.

 

[doesitonall4rs]

I may need to do that! Only problem is i run dsm link v2 so i dont have the boost by gear luxary!

I thought about dropping tire pressure from 30 to 20 but wasnt sure how safe that is on street tires.

 

[Dsmkauai]

I lunched my gvr4 with crappy street tires and lower the pressure to about 24psi cut low 1.8 60' that way. But I didn't want to go anymore because it still has the stock 3bolt still.
