Ran the initial break in on Dave Underwoods 404ci turbo engine today. 94mm single turbo with W2W headers. Turbo is running out of steam upstairs, but comes online solid by 5000rpm.
This is the All Pro cathedral port heads on a iron block.

HELL YEAH!i was following his thread in the dyno section way back when when he was having all those problems with his setup.Im glad he got it sorted out,but i didnt know he was going boosted too,back then he was just going on motor.

 

Hydraulic cam? Very impressive numbers . Is this going in front of a glide, or TH400?

 

Nicely done, but which 94mm unit are you running on that engine?

 

ddnspider

 

ddnspider its a diff car and diff motor but same owner

 

I'm looking to use a 94mm on my 509" BBC.

What are the specs on the turbo?

 

Ah gotcha.i thought he had a 427 too thats why i was suprised lol

 

holy schmoly! Great numbers W2W! That must pull like a freight train from 5-7K.

Is this with a GMPP carb style lower intake?

Liquid or air/air intercooler?

BigStuff3 fuel management?

Solid or hydraulic roller?

Dry Sump oiling?

What rods?

 

wow, impressive numbers!!!!!

 

Engine dyno?

 

Finally got that thing running... Now time to head to the track!!! Looks like it needs the bigger turbo after all to get max power but those numbers should be more than enough to run 7.80's and scare Dave to death!!

I'll answer some of the answers for Kurt since this motor is very similar to ours, It is a solid roller,Big stuff 3,and will have a rossler th210, and was on an engine dyno,as far as the rods im not sure, and it does use a carb style intake. Congrats to Dave, hes waited a long time for this project to finally get to this point. Now lets go racin!!!

 

bad ***.... More info Kurt.....
How is the rest of the build coming along???
Kyle

 

That's badass!

 

Just some rough estimates, but if the boost stayed on and torque stayed pretty much around 1200 up to 8k, that'd be over 1800 hp. Is that around what you guys are looking for? Badass!

 

hows harlans old kit coming homer

 

Rocking and rolling...w2w tuned it few weeks back. Love those guys they did a good job!

 

Thanks Steve,I can't wait to get the car out,might be heading south early next year.I know I'm not going to wait till April when Trails or Norwalk opens to run it that's for sure.May camp out in my trailer for a week at Orlando or Bradenton.

The car will be done in time to make the Detroit Autorama show in the first week of March.

Once I learn the car the 94mm will be coming off then it will be time to make some power.

The engine has a long list of cool parts
Jesel beltdrive
Jesel valvetrain rockers,lifters
Del West titanium valves
Mahle pistons
Oliver rods
Callies lightweight 4" crank
Dailey 5 stage dry sump
2" primary mandrel bent 321 stainless turbo headers.
Big valve race ported All-Pro heads

I'm sure I'm forgetting something but you get the idea.

 

That was my Z06 street car.This engine is going in my drag car.

 

It's a PTE 94mm.
