Too much for the street?
i currently make just shy of 1100 wheel and i want more. you can never have too much power. i run pro efi for the traction issue with that power so i can use it. there is nothing better than the look on a busa riders face when you pull them in a car.

Post like this give me inspiration. I feel my car runs good, but being down about 400 from guys like you in your range makes me realize that I need to keep pushing...as my car is still slow.
So my opinion and it sounds like a few other high horsepower guys is there is no such thing as to much for the street if you use available strategies to bring the power in a reasonable manner. My car only dynoed once at 770 on 9 pounds of boost because of a faulty fuel pump I didn't run it any harder but I run it now on 18 pounds all the time with boost by speed control run off the front wheel speed sensor. I also have the ms3 set up with traction control just in case. So whatever power I have isn't to much for the street but when my lower wastegate hose blew apart and I couldn't control boost yes 18 psi at 3600 rpm was hella scary and my life did flash before my eyes when I was pointed at that brick wall unexpectedly. It all depends on your technical know how and ability to tune these devices to make whatever hp on the street.

Mines at 690rwhp but needs the fuel return and rail feed altered, also bigger fuel pump from the 2ltr swirl pot to the engine.
Once sorted & retuned it will be over the 700rwhp
Driving with the fbw TB on say a 1/4 throttle is so easy, it's only when the right foot gets heavy that it becomes a problem haha!

it shouldnt depend on social status, if 400hp is fun for you, that's all that matters. 400 is certainly enough fun for me daily driving. If 400 feels good, there shouldn't be a need to expand it untill it feels slow. It just takes time to get used to it. If it were a drag car, grudge car..etc, then sure, 1400 hp is great.

What’s the difference between a F1 and a F1A ? I have the 5.0 ratio F1, isn’t the F1A a 5.40 ratio? Maybe that’s the difference?
I have a 01LQ4 70,000 miles
AFR225 heads
Cam???
F1 Procharger
FMIC
100% Meth injection
60lb injectors
Haven’t sorted the fuel pump(s) and feed/return system yet.
Thinking about going 370”
Good pistons and rods
LS6 intake and Ported stock throttle body
14-15 psi boost
T56
LT1-S twin disc
Tick master
MGW shifter
And a speed bleeder
Moser 12 bolt 3:73’s
35 spline axles
Girdle
I have everything in hand , except picking out fuel pump/ lines / cam .
Question is - is this too much for the street , it definitely is not a race car just a fun street car with Strano springs and full UMI suspension. (98 Trans Am )
Maybe 700 RWHP??

There are countless, literally COUNTLESS 1,000+ RWHP cars all over South Florida. Everyone races them on the street and has a blast......and everyone with those cars wants and needs more power.
I remember when a bunch of cheeseballs on this site and other sites back in 2002 told me I was an idiot for building a 500 RWHP 427ci for the street.......500 RWHP got boring in one week. And I realized after taking so many people for rides and letting a bunch of SO-CALLED performance enthusiasts drive my car......they are all just a bunch of scared-y-cats........
Make as much power as your pocket book allows....then learn to drive it properly and put money into suspension and traction. Better to have too much, then too little.

The age old question....what is too much. Well, there is no limit. There's only a limit to those who cannot drive a car very well...or those who frighten easily.

All of the newer F-1's have the same 5.40/1 gear ratio as the F-1A's. Different impeller design, inducer diameter and exducer diameter along with max impeller rpm. The F-1 won't make quite as much boost as an F-1A. Bob

I think for my project the F1 will not let me down. I don’t plan to max out this head unit .
You're welcome. It can indeed make a lot of power. Bob

I guess "Too much for the street" isn't really dictated by the engine, but more by traction. I have a 5.3 turbo (PT7675) in my 96 Z28. I got a deal on twin GT35's a couple of years ago and I'm getting ready to fab up the hot side for it. But right now, I can get into my fully licensed, inspected, 100% street legal car with it's M/T DR (317x35x17), let the air pressure down to 17psi, then drive to McDonalds, eat, drive the 15 minutes to the track, get inspected, drive into the staging lanes, stage and turn low 10s, then drive back home without going back to the pits. Just pull back on the road.
Accelerating (I'm currently at 19.5 psi boost) on the highways just feels something short of scary with the current setup, and the twins should just bring it on even earlier with a bigger surge as its wound out.
Yet, as the guys say here, you tell other car guys you're making less than 1000rwhp and they look at you like you just said, "sometimes I like grilled cheese sandwiches". They're not impressed. Even if you make 1,300rwhp, you are, in many of their opinions "just getting started". Lol...
I just know I'm extremely happy with my car and I'm sure you will be with yours too, no matter where you land in the HP spectrum.
