What Boost controller were y'all using?

 

Innovate SCG1

 

Dame that ones fancy. Haven't used one of those yet. Doesnt it control boost by afrs as well? What spring was in the gate? I'm assuming something over 11#

 

I have a Tial MVR and used the 21.75 combo in the wastegate. It was sustaining 16lbs down the track with a spike to 17.

 

So you have a 21# spring in the gate? And its only seeing 17# peak?

 

Yes.

When I ran the 10# springs it was only seeing 8.5# or so.

 

Yeah there is something wrong there. 21# spring should open at 21# not any sooner unless its a really really soft spring.

 

Ah okay, that makes more sense. Also makes more sense why you were able to add 6 degrees of timing without blowing something up...its running E85 LOL.

 

I guess I forgot to update this thread... she went a best of 9.7 and a best MPH of 140 last month! woohoo!

This was the third outing in the car and we have ironed out a LOT of bugs. First track day out, 11.0 at low 120s on spring pressure. Next track day out, 10.4 at 133 on 14-15 lbs and then finally today 9's!

First pass of the day I went 10.2 at 133. Matt Sorian was hosting the track day and was able to add timing and make some tweaks to my tune. Next pass:


9.78 at 136.95!



As you can hear in the video, its blowing out spark at the big end. We let it cool off, closed the gaps on some new plugs, put them in, and tried again.



THAT TRAP SPEED!

We backed that up with another 9.8 @139.5

I am so freaking stoked. This is a STOCK BOTTOM END GEN 3 5.3 that we opened the ring gap on, put my old 241 stock heads off my blue car, and an LS6 intake on and sent it.

Props to Huron Speed on an absolutely phenomenal kit that performs!

That's moving! Congrats! This thread makes me miss my fbody

 

Just read this entire post as I'm trying to decide between a Huron V3 T4 with A/C kit or a nitrous build. Loving the results and the car shows the hard work, time, and $$$ you've put into it. Hope to keep getting updates

 

Unfortunately, no good updates

There was a track event coming up in May/June so I wanted to get the car up on the lift and look everything over. While doing this, I noticed my passenger side axle seal was leaking pretty bad and decided it was probably best that I not go and that I finally have the gears changed out. Pyle Brothers, about an hour from me, does great work so I decided to put the "highway wheels" on (AKA some mismatched 17's that are sitting in my garage) and headed out. The car cruised the entire way down there between 70-85MPH with no issues, I even sat in traffic a few times.



It wasn't until I exited I-10, about a mile from their shop, that things went bad. The bolts holding the caliper bracket into my backing plates sheared out and I lost brakes. I dont know how I didn't crash or catch the car on fire. I literally pulled into their parking lot with the car smoking from it spraying brake fluid all over the hot rotors.





So this is how the car came back from Pyle Brothers, $200 dollars later.



So for the last 2-3 months ive been trying to piece everything back together. Wilwood would point to Moser and Moser to Wilwood so trying to get the correct pieces has been a PITA. BUT, i think with the help of my good friends, we got it sorted out. Since then, I've had some other projects pop up that have demanded some time so I haven't been completely without something fun to drive.

I picked up this 1986 Buick T-Type out of a field. Its been sitting for who knows how long. But with the help of the same friends that helped build the turbo SS, this Buick lives again. Its so much fun to drive.




Then the fuel pump went out in my NBM SS.



So add that to the list of things to fix!

But, in October we plan on going to the Buick vs Ford Shootout in Noble, Oklahoma. They have opened the classes to LS powered vehicles so I'm pretty excited to travel somewhere with my family and friends to race. Hopefully some good updates coming soon!

 

I wish I had better updates but unfortunately I do not. My family, and 99pewterz71's family trailered our cars up to Noble, Oklahoma for the Buick vs Ford Shootout (which is now open to LS powered vehicles). I had a tank of Ignite 114 Red in the car hoping to really crank up the boost and see what the car does. Unfortunately, didn't bring the laptop and couldn't adjust fueling car kept hitting the A/F cutoff on the SCG1. It made 16lbs and went 9.9 at 137. I had an absolute blast though.

I plan on going to a track rental soon before we lose all the cold weather here in Houston.

 

 

Been picking at the car some here and there, mostly driving it and just enjoying.

I started to take some time to start removing some weight. When I first got the car done, I put it on the scales and it weighed in at 3679 without me in it. Yesterday, it was 3539 without me in it and a little less than a 1/4 tank of gas.



First up was a MWC Light weight rear bumper support. From what I gather, it was about 25 lbs that was lost off the back of the car. I also began pulling out some dynomat. The whole back end of the car, all the way up to the base of the rear seats was covered. I was able to get the rear hatch area mostly clean. That is a 12lb dynomat ball, LOL.



I also pulled the corsa catback off to shed a little more weight for the track tonight. Turned it up some, put some Ignite 114 in it, and we are going to see what this Gen 3 5.3 can do!

 

We had a fun night at the track. Got to make 4 passes and even though the car didn't ET what I was hoping for, it definitely picked up some MPH. Best ET was a 9.80 and best MPH was a 142.6 and we drove it back onto the trailer. This SBE Gen 3 5.3 has been a trooper!

Waiting in the staging lines:



Time Slips:



That last pass, with the 1.5x 60ft, I pushed through the brakes and crossed the beams then when, but overall the car 60fts really well for what it is.

First pass of the night, for some reason my boost controller wasn't reading boost but I would guess it was still at that 19psi mark:


Third Pass of the Night, upped the gain on the boost controller and it was holding about 20-21pounds with a spike to 25psi when I locked the converter. BUT, I forgot to raise the boost cut off so just a little before the trap it bled off all the boost when it hit 25psi and it still went 9.8 at 142:


Last pass of the night, you can see it push through the brakes then I go. This pass it held around 21psi through the run and spike to 25psi when I locked the converter:


If i could get this thing to make 23-24psi throughout the run I think its gonna be down in the 9.6x neighborhood but I cant seem to get it figured out.

 

Getting there man @bluestreak98 . Why the spike BC issue or not enough wastegate issue? When does it occur?

 

@soloman369 For whatever reason, I cannot get my Circle D triple disc converter to lock via HPTuners. As a track fix we put it on a switch. So whenever I lock the TC with the switch, it will spike up.

I feel like we keep turning the screws to the boost controller but it just will NOT go anymore. When I made the first 9 second pass we had it around 20-30% (Innovate SCG-1) and on Friday night I had it all the way up in the 56-60% range and it just wasn't holding boost throughout the run. Ill post the video of the run with my GoPro pointing at the SCG1 so you can see what the boost was doing.

 

Ill read over that manual. Locking the converter prob adds the extra load that the gate cant handle probably then settles back out. Do you happen to have a log fo the runs?

 

Any help you are willing to give, I'm here to listen. We have plenty of logs we can send!
