The Horsepower Calculator - Version 3.8

I created a customer satisfaction survey last week and sent it to all of my existing free and paid customers. 
As part of the feedback from that survey, I'm currently working on writing revision 3.8 of the Horsepower Calculator...

This revision will include the following updates:

  • Re-writing the Engine Calculator to give cam duration recommendations @ 0.050" lift rather than seat-to-seat duration or advertised duration.
  • Extending the Turbo Calculator to perform more accurate twincharger modeling including new illustration and temperature modeling for post-charger and post-intercooler intake air temps

  • Extending  the Engine Calculator to recommend a different static compression ratio for intercooled and non-intercooled applications.
  • Extending Charger Database with links to compressor maps and possibly plotting demand lines on the maps
  • Extending the E85 Calculator to become a 'fuel and octane center'... this allows for an anything goes of alcoholic, non alcoholic and oxygenated fuel mixes, calculating the final mixture's oxygenation, autoignition, and flame front parameters and then using the data as an input into the Engine calculator for calculating compression ratios.
  • Increased user friendliness (remember my car & inputs, better placement of next/back buttons, email me the illustrations not just the data...etc)
So this is going to be a hefty but very useful re-write and hopefully will take the software that extra step from being VERY good to being remarkable... I'll keep you updated

Budget Boost

Just this morning I was reading a great presentation (80+ slides) on how Hyundai strategically boosted its image and brand recognition in the United States making it the #2 quality and customer satisfaction automotive manufacturer in 2006 after Toyota/Lexus (according to JD Power). 

These strategic changes included new interior quality, different engine design for optimized throttle response, and altered exhaust systems for more engaging lower frequency noise.... with this optimization of several very minor changes on an already solid car Hyundai was able to maximize the new owner's perception of the sportiness, comfort, control and quality of the car (for very little money invested).

What I like about Hyundai's is that they have a very passionate customer base that is interested in modifying and boosting their cars. This allows a healthy aftermarket following to grow around the Genesis , Tiburon and Coupe platforms allowing us to build up 350hp to 450hp boosted versions of these cars for very little money and complexity compared to buying an 'off the showroom floor' 450hp car. 

This year ARK is bringing a 450hp Hyundai Gensis to Sema ... The APG basic kit is a Rotrex C38-81 trim intercooled and a re-tuned ECU...using our Supercharger Calculator, and factoring in the 8whp gain on the naturally aspirated 3.8 from the ARK exhaust, then we calculate that the kit is running a modest 6.4psi to achieve this power goal, which is agreeable with the factory compression ratio of 10.4:1

ARK's Genesis kit takes the basic 306-horsepower, 3.8-liter V-6 found in the Coupe and drills it out to 450 horsepower through Mahle pistons, Brian Crower connecting rods, an APG supercharger with intercooling, and ARK dual exhausts and a high-flow intake manifold.

ProEFI and E85 Conversions...

I was using our Turbo Calculator and our E85 Calculator to help an old friend of mine confirm his choices for performance parts for his buildup. He is building an 800 horsepower 3000GT VR4 using a Borg Warner S372 single turbo, dual 38mm wastegates, 272* cams and an E85 Conversion using  Injector Clinic's FIC2150's ... 

During our conversation we ran into an amazing new engine management system by ProEFI. This system uses a GM style Alcohol concentration sensor mounted in the gas tank to linearly extrapolate between two tuned maps for your vehicle... the first map is a 100% gasoline fuel, timing and boost map, and the second map is a 100% Alcohol/Ethanol fuel, timing, and boost map...

Once those two maps have been dynotunes, the ProEFI system automatically figures out how close you are to either map based on what fuel you are carrying in your tank... and delivers the right amount of boost and power for that octane level.

If you're the kind of person that likes safeguards in your system, the system also comes with built in knock-retard in case something isn't quite right AS WELL AS a fuel pressure safety system that can detect a weak or clogged fuel delivery system, can detect a drop in fuel pressure and will put your car into a conservative low-boost tune accordingly to prevent catastrophic failure and save the motor.

I'm very impressed by this system because you can tell it was designed by the racers, for the racers as it covers power and safety which is what we want...

SBT - Small Block Toyota

Back in 1999, I used to own a 1991 Celica GTS Hatchback. On this car I started learning the mythical craft of automotive performance and eventually I turbocharged that car's engine and got addicted to boost... 

Having said that, John has a project that brings butterflies to my stomach and reminds of all the crazy and fun times I had in that little lightweight hatchback car.... Even though my car was plenty fast with about 180 wheel horsepower from 10psi running on a 2.2 liter engine, what we have here today is something that is not only plenty fast, but also VERY ambitious...

The car is equipped with a Toyota/Lexus 1uzfe engine (4.0Liter V8) running at 14psi of water injected boost and putting down roughly 350hp at the rear wheels...

A stunning Body-Off buildup

This is a great example of a body-off buildup for a 1981 corvette. 
The car is built from the ground up on a custom tube-rail chassis using a supercharged and intercooled LSX engine probably putting down close to 800 horsepower.

Amazing project, sad to see him sell such a thing but I hope it finds a good home ... 

Watch on Youtube

Porsche ITB's


In this week's tuner report we use our manifold calculator and E85 calculator to design a basic bolt on package for the porsche 928... this package includes:
  • Individual throttle body intake manifold
  • Long tube 4-1 header targeting a torque boost at 3200 rpms
  • Custom true dual cat-back exhaust system 
Click here for Tuner Report # 4 and watch the video on the design process
