Bolt-on HP estimates?
 

What are some good estimates the 2nd gen hp will be with all the 1st gen bolt on mods? Tune, header etc?

Do you think the 2.4 will respond better to mods?

In all seriousness I wouldn't be surprised if the new ecu has a few tricks in it to make tuning more difficult but I'm guessing 225 whp to be possible with e85 once the bugs are worked out.

My 17' hit 186/148 wheel on 91 with catless header and tune.

Baseline was 170/133 with header on.

Thats an improvement of 9% whp and 10% wtq

170 / 205 = 0.829 so about 17% HP drivetrain loss from stock
133 / 155 = 0.858 so about 14% TQ drivetrain loss from stock

Assuming next gen has close to if not the same drivetrain loss, 228/184 equals to about 189/158. Which is pretty close to my car.

Assuming we get the same gains from NA bolt ons as last gen and add 9%whp and 10%wtq we end up with 206/180 wheel.

Its been stated that the 2nd Gen does ~195whp+ on a SAE Dynojet which is similar to a E85 on an otherwise stock Gen1. It should scoot pretty good. JDM tuners already have their hands on them and it appears the ECU is just as flexible as before.

Better? No. Just has more displacement.

The only way it would respond better is if it was more conservatively tuned, leaving room for tuning. The redline is already the same with bigger pistons. Unless they fixed springs and oiling, there probably isn’t anything left rpm wise with just bolt ons and a tune.

Did they keep the same sized throttle body? That could use a bump maybe. I wouldn’t expect much of a difference overall besides displacement. It already is a high strung motor.

They use a larger TB. I forget the size but it was over 68mm I believe.

Thanks and Grams is 72mm.

I think Irace86's point is reasonable, but at the same time even if we get similar gains out of the 2.4L it will still be a good improvement over what the 2.0L cars get with bolt-ons. I think this will be very competitive in NASA and other racing classes (which the pessimistic-side of my brain tells me that will lead to NASA furthering the handicap on the 86 platform).

I am interested to see what the FI possibilities are on the new engine with more displacement but a higher compression rate.

Back when I modded my FRS in 2013 the Edelbrock kit wasn't out, that piece looks the business. I was just looking at some dyno charts for it. If I do decide to go with forced induction again, at first I was thinking about going the turbo route this time since I have more experience with turbo cars now than I did back then. But now....I would want to see what Edelbrock does with their kit first because that is a very nice, clean part that IMHO looks good in the engine bay.

It will probably be a good long wait before the tuners get really comfortable with the new engine though. I'm just speculating/rambling. :thumbsup:

Compression rate is the same as last gen. Please read the latest official press releases.

My mistake :bonk:

Still, that is even more interesting then. The 2.0 liter responded well to mods and forced induction. With more displacement + stronger rods I can't wait to see what the tuning shops can do with the 2.4.
