Who's ready for some 3800 power?!

[Daniel Jost]

Have you checked w/ Lonnie Diers on his adapters, to if he has one for the 3800's.

I talked to Lonnie a while back and he did a bellhousing adaptor for the 200. I have since decided to go 4L80E and was going to give the Speedway adapter a chance. I already have a trans adapter designed that looks just like the Transmission Adapters system and won't need trans or engine modifications. I am now considering having made. This is why I wanted to know what the failure mode was.

Thanks, Dan

I will get some pics. Local engineer was surprised it lasted at all being a 1/8th inch peace of mild steel we found out lol

sounds like a billet piece is in order forsure.

Hey delco about your set up , you were only able to get 19psi out of engine before maxing out injectors?

 

[delcowizzid]

We have run 21psi and 30+ accidentally for a 3/4 pass before the map sensor hose blew off and killed a headgasket lol we run straight 110/130 avgas so hard to detonate

 

[delcowizzid]

Now has ported heads and is getting lean at 17psi

 

[delcowizzid]

Old plate and New 10mm thick custom made replacement

 

[GBGN1]

Yeah that looks pretty cheap

 

[delcowizzid]

Yeah the speedway motors plate from USA lasted 3 years no issues and ran 10.8s

 

[GBGN1]

I'm surprised lasted that long. Maybe if it was stainless or really high nickel there wouldn't be an issue.

Could you provide a couple of pics of your setup? I just watched a 30 min video on the LN3 block on youtube. Lots of refinements on this block, it's on center, the injector placement. Beefier than the LC2 and the FWD block it replaced. Didn't realize how much difference the injector placement makes.

To damn bad they didn't keep at least one RWD with the 3800 through the 90's and turbo charge it.

We've been beating on this one 300000km engine with cam and springs for 5 years just went 10.5@129mph

Now that is weird looking set up.... I like it

Damn. Are you using the GMP4 ECM? If so are you familiar with the torque management feature? Did you have to disable it? Do you know how much your car weighs? Kilograms are fine, I can convert back to pounds. I'm really impressed with what you've done with this block and motor as a whole.

I really wish I would have looked into the 3800 series II or III block before I did my rebuild. The amount I have spent on the 109 block is crazy, considering the reliably. When I told my engine builder I wanted about 600rwhp with the build, he said if I wanted reliability I at the power level I should go stage 2 or TA performance. He advised me not to consistently push it to 600hp. The key word there is consistently.

With my turbo, 6265, I'll probably never hit 525hp. So I'll be good.

Once I get my GN done, I'm going to build me a daily driver with 3800 S2 or S3 block.

This is the video I stumbled on and I remembered reading that someone was using an LN3 block -

It reminds me of the hot air setup kinda, but flipped. I like it as well. How's it going with your 3800 project? Are you on the road or waiting on spring to come?

EDIT: It reminds me of IC setup flipped moreso.

Oh it's hot in Houston already lol. Just been busy buying new bumpers and fillers , weather stripping plus a lot more. $ you know how it gos . No car runs good. But I'm battling a idle stability issue. Moving the maf closer to the throttle body this week. To see if that helps. But of right now I'm entertaining the thought of selling the hp tuner and going with a full stand alone ecu. Dominator efi for the car so I can run speed density and have map up to 5 bar. But it's a little pricy.

We run a modified Aussie 1227808 delco ecu.non sequential injection batch fire jobbie.modified for high speed aldl and realtime tuning using gear from our website at pcmhacking.net .the only torque management in our ecu is for limiting power when you go from neutral to drive or reverse lol

Yes, I remember you saying that in addition to the motor you were also doing some restoration. Restoration can be expensive by itself. I hope everything works out with the ECU. I'm going to try and stick to using my stock ECU for as long as possible.

Did you know that there is a billet crank available for these blocks. I was looking at a girdle and I found this why searching. It says L67, but I'm pretty sure it would work on any series 2 or 3 3800 block. If you ever decide to go for a world record and decide to get this crank, let me know. Maybe I can get some help with contributing to the cost. I'm really interested in seeing how far a 3800 s2 or s3 block can be pushed.

Yes they have had that crank out for a long time. COME racing. They had a few issues with it in the past but looks like a nice unit. With the ability of the stock crank to hold 800hp imo not worth the money. Expensive piece.
