How many went FI and blew a motor?

That "safe" 500whp from GTM TT kit - how many would it be in BHP ?

Baer383

WHP is measured at the rear wheel.

Just go by WHP and you will be better off.

Typical loss from BHP to WHP is 15%-18% I believe.

2011 Nismo#91

Typically a stock Nismo gets ~290 WHP but is listed as 350 BHP.
83% makes it to the wheels. Or 17% is lost.


So lets say you modded it to output 500 WHP, working backwards is 602 BHP. Which is a hell of a lot of power for a production engine.

For perspective, some other production cars '09 and prior with around that power:
2005 Pagani Zonda F — 594 hp
2009 Bentley Continental Flying Spur Speed — 600 hp
2009 Bentley Continental GT Speed — 600
2008 Dodge Viper SRT-10 — 600 hp
1993 Bugatti EB110 Supersport — 603 hp
2006 Maybach 57S and 62S — 604
2005 Mercedes-Benz SL65 AMG — 604 hp
2006 Mercedes-Benz S65 AMG — 604 hp
2005 Mercedes-Benz CL65 AMG — 604 hp
2004 Porsche Carrera GT — 605 hp
2007 Ferrari 599 GTB Fiorano — 611 hp

162 hp/liter is massive.

Not for a forced-induction engine. The new Porsche 918 has a N/A V8 that gets 130+ BHP/Liter.

Well, yeah. If I could afford a 918 I wouldn't be here. Maybe I should qualify my posts a little bit.

I'd like to think that if I had that kind of money I would still post here. It saddens me that you feel we are low-class people unworthy of the company of those that have money.

Man,

Those are some crazy pictures! The pleasure and the pain involved with this sport. FortuneLSX-TT, you are very right about good shops becoming hard to come by these days. I almost had a catastrophe myself because of shoddy exhaust work. Luckily GTM resolved much of this. I am a believer that excellent, not just good, installation and conservative tuning are key on these builds. Did you build your block (pistons, rods, etc) after this incident?

I'm not convinced that 17% loss is constant for 290whp and 500whp range of power. I think that loss is different at 500whp.

2011 Nismo#91

Your right, some energy loss is constant regardless of the over all power. Like your coolant and oil pumps.. However some losses are added and or proportionally increasing with adding FI, additional turbines, bearings, etc.

Unfortunately I don't see anyone testing the BHP output of a FI'd motor anytime soon. The best case is just a constant loss of around 60hp would be like 560bhp worst would be like 610bhp. Something in the in between would be most likely the best guess.
