add on horse power

[sking]

what are some good add one horse power that do not require taking the engine out

[rich]

What motor do you have? What condition is the motor in? (how much compression, leak down,ect.) Is your fuel injection intact? Do you have smog equiptment? Or is the motor Carbed? You wouldn't want to start putting bolt on performance parts on a weak motor. It wouldn't make much sense....

[Otto]

I don't know of anything that you can add on externally that will give you a horsepower increase. Salespersons will claim all kinds of horsepower gains, but the dyno don't lie. Let the dyno be your friend and he will pull you through all the bs that is floating out there. If you were to put all the gas saving devices that are offered in the JC Whitney catalog, you would have a vehicle that would make 25 miles per gallon. Don't believe everything you read!!!!! Do you believe Jona was swallowed by a big fish, and the walls of Jerico were blown down with a trumphet?????????? It is in the widest read book on the face of the earth, translated in more languages than any book in the history of man. OTTO

Probably the biggest bang for the buck is a good complete tune up. Plugs, wires, cap rotor, Points, oil, air filter, valve adjust. check set timing, change fuel filter.
Change brake fluid, trans oil, check air in tires.
You would be amazed at what people don't do to thier cars. Not saying anyone here is negligent.

[Rouser]

Otto, I do believe you could've left out the biblical references to prove your point; they were both insulting and offensive.

Regardless of what your own personal beliefs might be, I would appreciate it if you not impugn someone else's in a forum such as this; it'll only peg you as rude and inconsiderate. I'm not a big P-C fanatic by any stretch, but this did need addressing.

After all, The Book might be the world's best seller for a reason ...

[Otto]

I am as much of a CHRISTIAN as you are. Spending my informative/growing years in parochial school. I did not mean to blaspheme the BOOK, just making a comparison. I should of said do you believe what you read in motormeisters ads. Sorry, I won't do that again. OTTO

[Rouser]

I apologize, but your comments didn't display any belief affiliation (um, CHRISTIAN like me); I wasn't challenging your religious background/instruction, only your choice of comparison.

Nope, I can say with surety that I don't believe everything I read in Motormeister's ads!

[DSPTurtle]

I thought it was kinda funny...both Otto's reference and the idea that you could bolt on HP. I was reading a rice burner advert and it referred to turbo chargers as "bolt-on". Yeah, I guess there are bolts that hold them on... JC Whitney, get it, JC.

Man, I am going to hell for that one!!!

[rich]

Come on guy's.... There are things that can be done to increase hp without the use of dyno. That's the point I was trying to make. But we just need a little more info to make a proper recomendation. On a sound motor, a simple free flow muffle can enhance performance. (It may screw up your fuel injection or emissions system) But There are things that are proven consistant. Then we could always install a holy water injection.

So sorry, really, so so sorry, I could help myself. The devil made me do it.

If the above offendsanyone I will promptly remove it.

There are a few bolt-on things you can do. Very few on the stock Type-4.

One is a good exhaust header and race muffler. Of course you will lose your heat, and about 600-1200 out of your wallet, for about 5HP.

Another is a custom turbo setup. Be prepared to fabricate it yourself and do tons of R&D and tuning, but the rewards can be very cool for maybe $500-1000 invested (not including a massive chunk of your time and brain sweat).

I'm no expert by any means, but beyond that there are not many "bolt ons" for the Type4 that do diddley-squat.

[Speedo959]

Otto, parochial shool?

[Dave at Pelican Parts]

OK folks--let's try to keep this on-topic.

Full-on race headers are your biggest bolt-on HP gain. That might be as much as 10 HP, but don't bank on it.

The best, and probably most expensive, are the Tangerine Racing (formerly CFR) headers. http://www.tangerineracing.com . A less-expensive (and less effective, supposedly) alternative can be found at http://www.kerryhunterenterprise.com . Triad up in Washington sells a set that is supposed to be between those two in both price and performance.

A good tune-up is probably the #1 "bolt-on" improvement. You can also monkey a bit with the intake--a K&N cone filter directly on the throttle body, or with a short ram-style intake, can give you a bit. Ditto enlarging the throttle body bore by up to 5mm. (Spendy, though!)

The turbo setup is technically bolt-on, but a lot more than most want to get into. It involves a lot of welding on the parts you are bolting on, as well as R&D and fab work...

"it'll only peg you as rude and inconsiderate."

Ha ha...a ha oh man. THATS all it takes to get that title ?? LOL

All this time I thought I landed that title by kicking peoples butt's on the track (much like John).

Back to the subject:

Take a driving class. It will add more Hp and torque than you could ever imagine.

Our 4cyl 914's are perfect learning tools. Much like underpowered go karts where you HAVE to learn about momentum.

It's no secret why some of the best drivers started out in karts. It's easy to add power once you learn to drive.

I dont think JC himself could find a Type 4 bolt on worth more than 5 hp. I think you get more bang for your buck by keeping stock engine well maintained. Otto does a good job with my stock 1.8.

I'm saving my pennies and praying for a 6.

[sking]

the engine is a 1.8 by the way and thanks for all of the info

[oredith]

someone say bolt-on?.. try this.. :P

14psi.. and rising..

the 914, back to "daily driver" duty.. :|

[Speedo959]

Oredith, now that is on the subject! Did you make that exhaust setup? I was planning on doing close to the same thing to an old set of exchangers that I had. I have seen setups that run all the way to the rear and then up front again. Heard that lag can be a problem.

[Racer Chris]

Sking,

Check out Grassroots Motorsports February issue. They tried a number of bolt on upgrades for 914. The Super Header will give you a huge boost in midrange torque, where you will feel it most. Guaranteed!

Also go to www.tangerineracing.com and email me if you're interested.

[JmuRiz]

Wow oredith, is that a custom job? If so, you should sell the design to someone and market that puppy! Keep up the good woth on the turbos. With you working the turbo angle and Jake Raby working the NA's...we'll have hot rod 914's all over this world of ours!

[oredith]

yes, the turbo was custom, built in my own garage, first with an oxy-ace torch, then with a mig (made things go faster, but uglier, wish i had a tig at my disposal)

i don't think i'd be into mass producing those in-my-garage.. though perhaps one *someone* on this list will have enough interest to work with me on it.. no real plans at this point though..

there's definitely A LOT of plumbing if the turbo system uses the stock HE, run all the way to the back of the car, than the turbo, than back to the intake..

there's also the problem of oil drainage if the turbo's placed in the back of the car right after the HE, the oil in most turbos are gravity drained.. it's hard to get rid of that oil if the turbo is at the same level as the motor.. and it also makes a -long- oil line to the turbo..

lots of people *think* about building their own turbo setup.. you guys have no idea how many e-mails i get with questions.. which surprises ME since i have no web-site setup.. every six months or so, i get a swarm of e-mails as the turbo subject becomes popular.. but when it comes right down to it.. not many people step up to the plate, because it's all custom.. there's no instant gratification.. and it means the 914 will be out of commission for a while.. so, as it stands, i think there's *still* only 4 turbo-914's.. 1 draw through (carb), 2 CIS setup, and mine, with the D-jet..

perhaps if a bolt-up KIT was made available, there'll be a lot more turbos on the road.. the idea sure -sounds- nice..

Hi Brad..
