After some issues with a bad transmission and a couple poor turbo decisions, I finally decided to get in touch with Mac of Speed Trapp Consulting, or better known on H-T as TheShodan. With his knowledge and some input from Brian of B&R Fittings, I chose to go with the Silver Surfer based off of my goal of a very streetable setup and nice powerband with a target HP of somewhere in the 400s.

From top to bottom, here we go...

Tuning was done by Jeff Davis of East Coast Performance in Jacksonville, NC and all runs were made on their in-house DynoJet.

A little hard to read, but official numbers were 515.60HP and 355.90TQ on 24 psi using 93 with a open downpipe.



The next run is more of the street setup. Not as impressive, but still fun. This was made on 19 psi using a full 3in exhaust where as the above run was an open downpipe.



Money shot...



And for *hits and giggles.



With it all said and done, the car is a blast to drive. Now I look back, it was well worth the headaches. I sacrificed some spool with the top mount setup, but it comes on so quick, you can hardly notice it.

 

damn that bay is pretty nice!

 

Wow that is impressive!

 

Sick!!!

 

Very nice setup. Not nervous about the power level on 93?

 

Nice. How di u put the power down on the street? BFg? 225 wide?

 

Thanks to everyone for the compliments.

@dcmatt - Its got a pretty conservative tune as of right now. The car might see 200 miles a month. I'm not too worried about the power level. AFRs look good. Plugs look good. I might end up doing a E85 tune next. Just have to find out who has it around me.

@olddohc - I normally run a 205/50/15 ET Street. That was mainly for 350-400 range. It does have a MFactory LSD, full-race traction bars, blox drag rears and boost by gear. I'm going to start dialing it in this upcoming week, but I see myself having to go to a 235/60/15 MH in the near future.

 

when I made 390 i had the nitto NTO1 225/45/15 it spun a tad in first but hooked no problem second and on, I had BBG too

 

nice!

im doing a teardown/rebuild soon myself with a surfer on a B20 non vtec. so this makes me excited about the powerband.

nice build and ride u got

 

amazing numbers! Nice job Mac!

 

Great numbers another Silver surfer satisfied customer for Mac. Thats a clean *** engine bay too. I need to take some time to clean mine up. Its cluttered with a/c crap though lol Good job on the build !

 

Damn nice numbers and nice build! Wish I could see the pics, but uncle sam has them blocked once again!

 

i'm trying to understand dynos a bit better these days..can someone tell me where the spool and full spool occur on this graph.

 

Thats a bad *** street setup right there. Congrats on the numbers.... now enjoy!

 

crazy numbers, congrats on the build definatly worth the headaches.

 

Congrats bro! Mac is awesome, always down to help with questions. Also will go out of his way for those that don't even purchase from him. Glad you met your goals!

 

Ps what is the silver surfer? The turbo?

 

^^^ yes silver surfer is the turbo. When are we gona see some vids of this beast

 

Sick bay.

 

any street video. Love to see how the response is...thanks.

 

Why is the tq falling off after 7k? I would think this setup should see the tq taper off around 8k. What size turbine housing is on the turbo?

 

 

The housing in this case wouldn't cause the "taper".. that's the camshaft in this case that would be the cause.

 

What is there to google smartass? Itr cams are not enough for a 84mm bore is that what your saying Shodan?

 

here smartass.. since you incapable of doing the searching..
