most of the podium SoCal AWD guys are only pushing atound 400-550whp. Its all about the balance of the car too, such as suspension, weight, tires, etc.

 

I also nominate the AMS 2.3RR engine... with possibly their GT850R setup

They rate it as having the potential of over 700whp on race gas with full spool on the stroked engine at around 3700RPM

 

With over 700whp at your disposal around 3700 RPM on a 2.3RR from AMS I would think thats plenty of power to podium. I agree with others though. If your total budget is 20k I would NOT spend 15 on the motor. I think 10k would be motor, think about susp. and braking.

Unless your MOTOR budget is 20k, that changes things quite a bit.

 

What class are you planning on running?

There is such thing as too much power for the tire allowed per class...

and

power delivery... responce.. power band mean more than a silly peak number

 

I just thought he would have a hard time hitting 800whp without it and anything bigger then a HTA86 would be to laggy for time attack cars. I don't even now if 800whp is feasible for a track car, that is ungodly amount of power and you would have to be a fantastic driver to truly enjoy a car that fast. I think it would scare the **** out of 99% people trying to do time attack events with that.

 

AMS has the most success in Time Attack and is proved time and time again to build reliable, race-winning cars... so, if I had 20k, I'd tell AMS to build me the most capable time-attack evo within that budget.

 

A couple more things...sorry for the confusion, I do not have a AMS 2.33rr and CNC head. That was just my suggestion for the ultimate road race car. AMS thinks so to because that is what the RR stands for. So I don't know what I wrote to make you believe I was running that set up I apologize. I WISH!

Also if your budget is 20,000 and you want an 800whp time attack car you are DREAMING!!!! Impossible, no way in hell. The Engine alone would be close to that, not including the 3000 dollar clutch, 5000 dollar turbo kit, and that just the start. Take a look at ALCON stasis brake kits that would be a third of your budget right there and I wouldn't take anything less with a 800whp time attack car. Then we have tires, fuel, pads, maintenance. The AMS TA car had well over 100,000 invested into it. So I think you need to reevaluate what you really want here. A stupid fast car or a very fast time attack car your not getting both.
Here is a more reasonable option for a Time attack car. This should handle and stop like a dream with mostly likely 500+whp

Robi Spec Advanced Suspension Package with KW Competitions
Alcon Stasis Front Brake kit SS Lines, Motul and obviously front and rear pads.
FP RED (all the bolt ons) I'm sure you now what that includes. Ask if you don't
CNC Race HEAD
GSC 2.2 with some aggressive cams pick your flavor (JUN, GSC, Kelfords, or Buschurs<need an EMS or Mellon to tune these)
I would also suggest a full race (if you can still afford it) exhaust manifold or JM exhaust manifold and I nice Intake Manifold like the AMS F1...
I would also recommend E85 in order to reach the high boost levels needed to get over 500+ WHP. If you cannot get E85 were you live at least get a race gas map.
Hope this helps

 

Wouldn`t that amount of power in a track car require ultra heavyduty everything throughout the drivetrain: Clutch, axle shafts, differentials, tranny, driveshaft, motor mounts, and, etc.?

 

I guess that it was my bad assuming that the final sentence in your post was your modlist, sorry. And it got you inducted into my Hall of Fame. I was envious though!

 

Haha yeah that would be my dream having that engine and turbo kit and yeah depending on the torque, a lot of money would be spent just to make the car handle the power

 

Wanna buy a fs635? Better top end then the HTA 35R.. I know a friend who likes money..

It's the second best turbo out there right now behind the hta86

 

hope you all had a wonderful Turkey day!!


thank you John for the honest evaluation.
JUST TO REITTERATE-THIS IS NOT MY CAR...

MOST of the items are basically taken care of suspension and chassis wise. the driver has plenty of "ins" with major manufacturers such as Tilton, FP, and others.

Fuel will be race gas albeit VP import or others. Fuel does get expensive QUICK. one weekend racing could be 500 bucks just in fuel FOR THE CAR that doesnt include the truck pulling it...ugh..

okay, now that i have seen some TURBO options, no one has suggested what INTERNALS and why. like i said in my original post, if i was looking to BUILD the engine, what parts would you buy and why. the 20k figure is preliminary at this stage. we have alot of fabricators and vendors on board already that are interested in this project, however, money for them right now is shallow. so is ours. THAT is why this makes it a challenge.

keep up the discussion. alot of great info for all here.

 

What sort of suspension, and chassis mods are done then?

If this was all going on your Helix coilovers I wouldn't reccomend much over the stock turbo...

When it comes to races you need to finish and when it comes to championships you need to finish up there every single time on a variety of tracks.

I'm not a big fan of monster 2.3 stroker/GT35 circuit setups because I've never seen a reliable one in my life (for whatever reason). I'd speculate it's about the increased stroke putting the engine internals under too much stress at high rpms or something but I'm no big expert....

Instead I'd go for a higher revving, prebuilt Tomei 2.1 or Cosworth 2.2 "crate motor" with all the extras - top notch internals, built head, aggresive cams etc. Drop that right in the engine bay, stick a JMF intake mani and big injectors on one end and a ported stock mani/FP Red on the other end, hook it all up to an AEM EMS, tune it, fill it with C16/E85 and away you go.

Whipsnap spoolup, excellent transient response, a huge, flexible powerband, and lots of area under the curve...likely coming in at around 450- 500whp without too much effort or strain on the motor.

With a reliable motor it's easier to spend time and effort on the little things like suspesion/chassis setup and driver development etc. that can also grab you precious seconds on track.

That's just my own dream circuit setup though.

 

I agree with those that said power is not everything. A lighter car can beat the heavy Hp monsters any time of the day on the track.

Building a Winning car is going to take ALOT more effort into the chassis IMO. You should work on that before building a 800Hp monster motor...because your going to need to slow that thing down and take corners at very high speeds. A $15,000 motor and $7,000 turbo kits looks nice..but not after you go off the track.

...but other then that, good advice on motors..
