OK I am looking for a couple more horsies. Check out my fquick garage to see what I have done. It dynoed at 392rwhp and 389rwtq. Did I miss anything? Could the little things get me a few more??? Any easy cheap suggestions that I am missing?


Thanks guys.

 

ported TB. it's good for about 8-12 ( little iffy on 12) HP. I'm doing mine soon. also, gears

edit- nice car btw, I like the 3-piece spoiler

 

OK theres one thing. Thanks for the compliment. Anything else?

 

underdrive pulley

elect water pump

SSRA

turbinator

 

I bought an underdrive allready. When the water pump takes a ****, or I have it off for something else I will do that. SSRA, is that the best one?

OK so combining lists

1. underdrive pulley(allready bought)
2. smooth bellows(forgot to mention in fquick)
3. electric water pump
4. SSRA
5. ported TB
6. TB bypass
7.


Gears will come later, but that is actually probably going to hurt rwhp.

Keep em coming

Forget about the smooth bellows - that's a cosmetic thing - no power to be had there.

What kind of dyno? What heads are you running?

I'm unfamiliar with the B&B exhaust, but I'll guarantee that a cutout would be worth another 10 at the wheels easy!

 

The heads were done by a company called CNC here in Florida. the specs are there to the best of my knowlege. I got them used/freshened

Here are my runs before and after then on spray.

 

That an auto car?

I see no mention of a clutch or anything like that.

You'll probably break 400rwhp with a ported TB and other little things... not too bad for an auto car.

 

No its a 6 speed. And that is STD too.

 

Dyno Numbers don't mean much if they aren't SAE.
STD shows higher numbers.


397rwhp (which is probably around 38x rwhp SAE) is honestly pretty weak for a heads/cam 6-speed car. It's actually on the lower end of a cam-only car. You definetly need a ported TB on that thing and might even need another clutch to hold the power. What injectors? What fuel pump? Who tuned the car?

A write-up on SAE vs. STD:
"SAE (Society of Automotive Engineers), USA. Power is corrected to reference conditions of 29.23 InHg (99 kPa) of dry air and 77 F (25°C). This SAE standard requires a correction for friction torque. Friction torque can be determined by measurements on special motoring dynamometers (which is only practical in research environments) or can be estimated. When estimates must be used, the SAE standard uses a default Mechanical Efficiency (ME) value of 85%. This is approximately correct at peak torque but not at other engine operating speeds. Some dynamometer systems use the SAE correction factor for atmospheric conditions but do not take mechanical efficiency into consideration at all (i.e. they assume a ME of 100%).

STD or STP. Another power correction standard determined by the SAE. This standard has been stable for a long time and is widely used in the performance industry. Power is corrected to reference conditions of 29.92 InHg (103.3 kPa) of dry air and 60 F (15.5°C). Because the reference conditions include higher pressure and cooler air than the SAE standard, these corrected power numbers will always be about 4 % higher than the SAE power numbers. Friction torque is handled in the same way as in the SAE standard."

How are you going to do that??? You going to pay him what it costs to get and install a cut out if it doesn't get him 10 rwhp??

A B&B Triflow is a very good catback. You don't hear much about them because they are very pricey. And I doubt that he would get very much from a cut out at his power level. He could, but I sure wouldn't bet any money on it.

 

SAE to STD is 5%

Actually most of the issue is in the heads, almost always is. Very few CNC programs put any consideration on what intake is bolted to the heads, they want to make sure the intake port cleans up so they make it much larger than the stock intake manifolds. You could probably take a decent aftermarket casting and gain 20hp easy.

It could be other places, I have seen cam only stuff run 420+rwhp SAE with 9" rear ends.

the SAE number was 381 rwhp. i have the files.

 

Cams are cheap, I may try a higher lift cam next. I got that damn Triumph almost out of my garage, so I will have more room and time soon. I am also looking at a bigger TB and maybe an intake. I doubt I will be buying heads til I get the money to do the big cubes.

 

You might want to get a tune that isn't crap. Have you looked at the A/F ratio in you dyno pulls. It's all over the place. I gaurentee you'll pick up some power if it's just tunned right. A/F ratio should be flat around 13.
