Even the dyno wasn't on your side.. i love watching your videos, you should have a printout of your dyno sheet in your car laminated so next time you beat an LS3 you show then you've only got 270hp at the wheels. that'll be a sight to see. LOL

It was making 284rwhp with the wastegate unbolted, the three screws, nuts and washers vibrated out. I was only making 8lbs in 1st gear, lag was horrible and the top end was depressing. I have since Dynoed 355rwhp. With 284hp he put a beating on me in the LS3, not anymore

I know. It's cool. I have a lot of safety and suspension mods, just a chip exhaust and headers on the engine side. but on the plus side I did smoke a Mustang, Saab (wtf- I know) and several Miata's. The 370 and 2 400+ hp Evos did get the better of me though

We win some we lose some. Its all for fun!

blah blah blah. i love the look on the guys faces when they get caught in the wrong gear ( perhaps over confidence ) and i blow by them! (even just for a second) especially that gallardo...what a moron.

Cd doesn't tell you anything without also knowing the car's frontal area (total drag is Cd * Frontal Area) and it really doesn't come into play too much until you get close to Vmax. Maximum engine RPM is likewise rather irrelevant.

A breathed-on 951 should be in the range of 275 hp and 300 ft-lbs at the wheels based on dyno sheets from mine. Assuming a 15% drivetrain loss, that's about 315 hp and 345 ft-lbs at the crank. The 951 weighs in at just over 2,700 pounds.

The NISMO Z is a bit of a porker at 3,300 pounds and is down on torque.

I can see a Z pulling away a bit on the basis of gearing due to the 6-speed transmission, but there's no a stock 370Z, even a NISMO, should walk a breathed-on 951 like it was standing still. Throw some mods on the Z, however, and all the flab on those cars will start getting mitigated really quick and we'll be breathing exhaust.

The class that the Z is in is for heavy modified cars.. the next class for him is full race. so he's FAR from stock
btw I saw one of his vids where he missed a shift and the motor went to 9k rpm.. and he just put it in the right gear and kept going. I would have been sweeping motor parts off the track if I did that

I have a "tuned" car. chip, headers, exhaust. A couple weeks ago at the track, (while in 3rd gear at full boost) a 370z went by me like I was tied to a post. Simple fact is you aren't going to compete with most of the modern cars out there, STI's, Evos, practically everything now day has 300hp stock.

.. Heu... are serious about what you said?? Are you sure you dont drive with closed eyes!?

I think something is bad with your car or maybe the driver..

Its sure if you have 300 HP VS whatever the car with 500 hp.. this is the effect you gonna have to get sticked to a post.

Plus I dont understand your "no body has a 944 of 4-500hp". Heu.. YES! You will spend money but you can make it.

Take exemple on this 951. Its approx 4-500hp.

In that case, all bets are off.

See above. The other car was one step shy of full race. He was simply pointing out that a 951 isn't going to be the fastest thing at the track anymore.

Read what he wrote, and this time pay attention. He said that no-one had "tuned" a 951 to 4-500 horsepower. And that's absolutely true. Getting 400 to 500 hp out of a 951 requires a hell of a lot more than just a "tune." For those numbers you're getting into things like a stroker crankshaft, an aftermarket turbo, and a custom engine management system. That's not a "tune," that's a full race build. A "tune" is what he described, little more than a chip and exhaust, things that can be done without ever opening up the engine.

Tuning includes this kind of modifications too sir. I think i'll give you the exact tuning definition from Wikipedia

Car tuning is both an industry and a hobby, in which an automobile, motor bike, scooter or moped is modified in order to improve its performance, handling and appearance and improve the owner's driving style.
[...]

2 Areas of modification
2.1 Audio
2.2 Interior tuning
2.3 Engine tuning
2.4 Suspension tuning
2.5 Body tuning
2.6 Tires
2.7 Detuning

1) Wikipedia is not a good primary source.

2) The phrase "engine tuning" does not mean that any work done to an engine is a "tune." Adding a chip is a "tune." Replacing the crankshaft is not. Just calling chipping a car "engine tuning" doesn't change the fact that adding a stroker crank is not a "tune."

Sorry kiddo, but when you talk with people who have decades of experience, a "tune" is something you can do without having to crack the block and you're just plain not going to get a 951 into the 400-500 hp range without a full on race build for the engine.

[FRZ951]

Kiddo!? Heum.. ok I think just for that the subject is close for me.

Aaron covered it very well. But in addition, I do in fact drive with my eyes closed.. my instructor noticed it several times and advised me not to. My lap time started to fall after that.

secondy, there is nothing wrong with my car, my Mom says it's perfect.

thirdly, I admit I'm no Mario Andretti. but I know when I'm being out driven and when I'm out car'd. Simple fact is 951's are not fast anymore. period. yeah, you can throw money at them and make them competive, but in the end you will just barely be holding your own against many modern cars delivered from Nissan, Subaru,Mitsu, among others. Then if those guys decide to upgrade their stuff, your all done.. I love my car but I can see it for what it really is and isn't

[FRZ951]

Pete, I agree with you. Many other cars are "superior" now but for exemple a 951 1988 cars, they are very amazing.

P.S: Don't take my previous mad with the eyes closed, I was just kidding

[Pete R]

exactly, NO other cars from the 80's were even on the track let alone going by me. 951's are FAR superior in that respect. The OP wanted a comparison to modern cars.
No offence taken, I don't take words on a message board to heart.

[FRZ951]

lol :P

[rick13]

Tires and Brakes win races!

just my nickels worth

[FRZ951]

Of course this is very important

I'm sorry but I have to agree with the others here. All motors are tuned, but in common terms a 'tuned' motor is accepted as one that hasn't been opened up or had big turbos , big cams, new lighter pistons and rods, standalone etc added. A chip and dual port wastegate is considered a tuned motor.

Whoever said that a 951 weighs 2700lbs is a little optimistic. They come stock at about 3000lbs. Then add the usual bigger wheels / tyres / brakes. To get one down to even 2700lbs takes a bit of dieting.

btw, the Red car in the link you posted only had about 350bhp...but it was much lighter and had bigger rubber (slicks) and wings. This is why it could compete with a Cup Car.
