Any Ideas to increase HP on 00R

[Saleenrose]

I work on allot of cars, recent is a Viper open track car, he would like to open track with me. The problem I have is the vipers and Vets of modern day have big HP numbers. This Viper did 450RWHP before I changed the cam and heads. I will dyno in a week. Same dyno, Mine, showed 385RWHP in my 00R and I weigh more. How should I go about increasing power. I did not really want to change the car before but I enjoy running it, it is a race car? I was thinking of value but decided what the F###. I have a 3100lb race car but it just does not seem the same. Any ideas to get this thing to 450RWHP, cams, ported heads, long tubes???:shrug:

00R horsepower

We installed the bassani x pipe and Bruce's 90mm MAf kit.. My car dynoed 404 RWHP. I think getting to 450 will be VERY tough. Scott

A custom built engine, talk to one of the big modular builders such as Al Papito (I think I spelled that right). They should be able to get you what you want but I agree with Scott that you aren't going to get there with just bolt on parts.

Scott,
Does your x-pipe have cats?

 

[Cypher-M1]

well there are a few 4.6L guys that have made 400whp with the right boltons, and a good choice in ported heads, cams and ported intake mani. I wouldn't be surprised if a R can get least 430's.......then again I don't know how well tuned/designed the motor is from the factory. If they have the same cams as the Mach1/terminator then a ford GT cam swap or 2001 cobra intake cam swap would help a little.

 

[Saleenrose]

Already have Bassani Exhaust, no cat, 90mm intake, custom tuned. Remamber these were dynoed on same dyno, most dynos very, so my 385 and his pre-450, now I asume so far will hit 530, are in sink. I am looking for info on heads cams porting, Maybe long tube headers?


"If they have the same cams as the Mach1/terminator then a ford GT cam swap or 2001 cobra intake cam swap would help a little."

Wrong Motor with that stuff. The ford GT stuff I dont think would be right for a NA motor.

Cat, whats a Cat? :rolling::rockon:

Don't forget that you're comparing 5.4L to 8L of displacement

Driver mod and suspension mods are WAY more important than power mods IMHO.

says the man who upgraded to a blown 5.4....


saleenrose talk to fourcam330, and al papito. fourcam has one of al's engines in his 98 svt. its a 5.5(i believe its based off of the 5.4r block) 550rwhp monster.

talk with bruce on suspension there are a lot of different ave you could take to improve lap times. :beerersonally i like griggs.

Actually there are, Remember the marauder and Mach1 and Navigator are all N/A...yet the 03-4 Cobra have the same cams, and 9 sec 03-4 cobra are running the 01 N/A Cobra cams. GT cams are starting to be a popular swap since they only coast about $450 for the set.

Your car should dyno just over 400 with the catless Bassani and the 90mm intake. That's on a Dyno-jet. If not, then you need a little help in the tune department.

I would not mod a Y2KR motor other than what you've done. They are perfect right from Ford! :rockon::bowdown:

IMHO, I agree with you completely Bruce!!

It is going to be hard to compete with a car that has 588 cid:rockon: (viper) and maybe 427cid (vette):sleeping:..

If you just have to do something to it, stick with the mods you are refering to. Have the heads ported!! These are the best you'll find, but there is a little left on the table. I don't have any numbers to back this up, but after talking extensively to Andy (fourcam330) and some others, I am willing to bet you would see a gain of 40-50 rwhp out of a full race ported head.

If you have the $$$ just laying around, go by those new-fangled Jesel roller-rockers for it, I think they are like $2500 or so.. I think a custom set of longtubes from Stainless works would be a great addition, probably good for another 25 maybe 30 rwh.. around $2500 for a custom set.

IMHO, I would not change cams, the R cams have plenty of gitty-up. They have a lift of .512", it actually does not need that much, probably like something like .475 You may get a few more ponies out of a custom set, but I don't think it's worth the money ($1000-1200) to do a cam swap. DO NOT use Ford GT, 03-04 Cobra cams, or anything like that... You will just be undoing what you are trying to accomplish, Those cars are blower cars..

I am willing to bet $50, that you can get at least 450 rwhp out of the R with nothing more than ported heads & longtubes and the mods you already have.

Please keep us posted of your progress!!

Have not raced him yet, I am pretty aggressive when competing, I have not changed any suspension, I do run 315 35 18 Victor 710s, the track he would like to have me go to is Miller Park, the straights are long and HP is a factor. I hate to change the car much but I also love to "mess" with expensive cars. Just thinking the R is getting "old" when you look at what "new" is out. PS I have found my dyno reads about 10-13% lower than a regular Dynojet, it is a loadcell Dynojet. Adding 10% back in puts me about the same as others. I can redyno and try again because those who say they are perfect all the time, most of the time are not. I may have left some on table.

My 2000 R made 470rwhp on a dyno dynamics dyno with custom longtubes ,a 90mm mass air , a custom diablosport tune and some 12.5 JE pistons. The heads and valvetrain were stock.

^Now we're talking.

There is a guy in VA who installed a vortec on his car and is making close to 600rwhp. Would that be enough?

 

[Saleenrose]

Thought about supercharger but was considering heat on track, last year raced against several GT500s and Ford GT, Driver needed Help, and was able to pass all with ease I believe due to heat soak of the supercharged engine. Great HP for short time. I think to start I will redyno and tune more to see what I can find, maybe long tube headers.

:beer:I just have to say that I love the fact that you guys aren't afraid to modify these cars and drive them like intended.:beer:

Maybe a turbo or two instead:shrug: I don't think they have those issues as much on track as long as they are done properly:thumbsup:

What altitude were you dynoed at?
Are you willing to always run race gas?

As previously posted a set of high compression pistons, fresh valve job w/ minor clean up and a retune will produce large gains ... with not much else needed to be changed.

Compression makes power EVERYTIME!

BUT you will have to run a high octane fuel ALL THE TIME.
