NRE Twin Turbo 515 BBC
 

Here's a few pics of an all aluminum, reverse cooled, hydraulic flat tappet 515 BBC with twin turbos that Nelson Racing Engines built. It made 1100HP on 91 octane and 1850HP on 109. It idles at 750 RPM.

Videos coming soon. :thumbsup:

What are the dimenisons on that intercooler? It looks tiny in the pictures!

Also, what kind of car is it in? Judging by the fenders, it looks like quite the sleeper...

I am no expert but I can't see only changing fuel spec would make 700hp more. No doubt by changing fuel they can change mixture curves and timing curves and gain a bunch but I clearly can't see or understand that much of a change unless the boost knob was turned up with the 109 and down on the 91. Please inform this young grasshopper.

You got it. High octane = more detonation resistance, which means you can run more boost, put in more fuel to go with the additional air, and more timing... and that means more power. Lots more power.

:eek: That is nice!! Looks like it was planned out well. Everything fits just right! :thumbsup:

Cool! What kind of car is it in?

Amazing, simply amazing!!!!

how much do you think one of those would set you back?!?!?

thanks Chris.

wow..........

A very quick one!! :yes: lol

A 57 Chevy.

Wow. Man that is one nice engine. :thumbsup:

MINE! I wish. :( What a gorgeous engine. Forced induction rules! :hail:

THATS INCREDIBLE!

Mike

Nelson is going to give hard times for "old" names .. Awsome work!! Can we please have more info..

For once I'm surprised it's not going into a "69 Camaro" LOL!! :D

Gotta to love them tri-fives!!

Killer engine!! Have any pics of the car? ?

They do some of the cleanest work I have seen.

Ridler contender
 

I had heard through the grape vine that there was a 57' being built for the Riddler. Supposedly the car was at Nelsons having the engine done, I image that this is it.

(holy crap)

A few more TT pics; this is a 350...

Turbo Tom
 

Looks nice Tom,
So who has some video footage of someone actually standing on it!
I'd like to meet the psycho that's willing to make a street quarter pass with that under his foot.
Let me know if you need a co-pilot!

wow, someone is going to go REAL fast, i would imagine a serious tub with some big ole ET slicks. i mean, 1100 on pump would be hard enough to drive. any idea what tranny? lenco? powerglide?

Any clues on cam specs or the boost level at both power level? What size are the turbos?

Andrew

The Motor Is 8to1 Compression The Cam Is One Of My Stage 1 Big Block Cams Very Very Reliable.the Motor Has Twin 80 Mm Turbos
If You Look We Made The Intake/ Valve Covers /and Timing Cover From Solid Billet Chunks Of Aluminum.weve Mounted The Water Pump To The Radiator And Reverse Cooled The Engine Running The Water Past Ex Valves First Then Into The Block.the Motor Runs 14 Psi On 91 With Not A Hint Of Detonation.and 31 Pounds On Kill We Made 42 Pulls At Way Over 1000 Hp Took The Pan Off And Checked Things Out The Bearings Didn't Even Look Like They Ever Were Taken Out Of The Package Before.it's Truly Amazing What Weve Been Doing With The Turbo Stuff Lately.last Week We Drove A Customers Car To The Track 1hour And A Half In Traffic 100+degreees Raced All Night 12 Passes And Crused Home Loafing At 1600 Rpm At Around 85 Mph Getting 20 Mpg.the Car Ran 139 Mph On 91 Octthe Motor Was Only Making 775 Hp.spinning The Tires At Over 100 Mph Steering Down The Track .a Modified Viper And 3.8 Porsche Went With Us.and We Could Pull Away From Them Like They Were Standing Still.these Are Definite Pro-touring Motors Of The Future.

Thank you mr Nelson for your personal update! I am sure there will be lot of market for reliable street turbo kits /engines. Just keep sending more pics :yes:

I think he just solved my dilemma...
Do you guys sell just engine parts? I know you guys like building complete motors, but for example, could i send you my heads, give you the motor spec and have you build a valve train for it? or have you send me one of your cams..

go to www.nelsonracingengines.com for details and his contact info

make sure to check out the rad video from the dyno!!!

Its No Problem You Can Send Me Your Heads .and I Can Build To Suit Just E-mail Me Or Call Tom Nelson

That's one amazing looking motor.
I hope to see it in person one day out there.

Congratulations on your building skills and discipline in fabrication, quite an an accomplishment in this life.

Rick :patriot: :thumbsup: :cool: :hail:

Sounds awesome...what kind of car and combo????

Hmmm...With that kind of power....time travel....may indeed....be possible...

Jeezum crow that's a lot of Wheaties.

New NRE Dyno Videos ....crazy!!!!!
 

Nelson Racing Engines has some new video footage on their site...holy crap 2,000hp !!!!!!!! :hail: NRE Videos

Are the turbo headers and down pipes on that car stainless or Ti? They have that bronzeish look of polished 6-4 :hail: :hail:

oh yeah and thats freakin awesome :thumbsup:

That is a wicked motor :thumbsup:

is this the car scott schnecloth ( not sure how he spells it ) is building ?

The car in bare metal looks absolutely sick. :hail:

Down the road I'm sure there will be pics - after it debuts at the Autorama.

That's what it's all about! Keep up the great pioneering work Tom, I'm following your foot steps with my 472ci sb TT. :thumbsup:
