Soler Engineering Throttle body

[NGOT8R]

I was able to get the throttle body installed today. I thought I would have had it done a long, long time ago, but I’ve literally been fooling around with installing my Steeda axle back all day long . Anyways, the car started right up and I was able to do the two idle sessions. I think I might be good. Looking forward to some road testing. I’ll report back here once I’ve had a chance to drive the car.

I was looking into the "rework your own" option while the car hibernates for the winter but it seems they are not taking any orders at all.

Alright ladies and gents, initial feedback:

I put the SP TB on Saturday morning after my first session - ambient temps were about 55 by this time. Car started up fine, no issues. Took it out on track for the first session and I could feel it before I event left pit lane. The first area of improvement (AOI) was adding throttle from idle--the engine just responded faster. It's hard to convey through words but it's not that the throttle feels more sensitive, it's that the motor revs from idle to whatever RPM you're calling for more quickly. It's mechanical, not electrical like a tune/pedalmax. So, first improvement is taking off.

Second, I also immediately noticed the engine is more responsively when on partial throttle. To the point that when I would hit bumps in the track I could hear the engine respond to my foot accidentally adding a bit of throttle. I never had this before because there was always a little delay as the TB blade opened and air made it into the intake. This TB makes the car a lot more responsive at partial throttle. Put bluntly, it feels more like a cable driven TB with a real snappy engine. This took a bit to get used to, but once I did, it meant it was a little easier to use throttle to set the car or swing the ass end out for a bit of a drift. Me likey.

The third and most noticeable AOI for me was downshifting. They felt both snappier and more consistent. At first, I actually found myself overreving a couple of the downshifts because by the time I got the gear change done, the engine had rev'd higher than I was used to. But once I got used to it, I found myself downshift earlier in my brake zones and utilizing engine braking more effectively. I also spent a session hitting really high downshifts on the back straight that were super predictable--I'm talking going from 7k rpm to 8k rpm on the 5-4 shift. My downshfits were clean the rest of the weekend after the first session with it. Highly recommend.

I only had two hiccups-

1. At one point during the first session, the car hiccupped a bit on partial throttle after a 4-3 downshift. Basically, I got on throttle and the engine kind of choked for .5 second before getting back to normal. There's a strong possibility that this was related to the clutch/throw out bearing as I have been having issues with high with some high RPM shifts because the TOB needs to be replaced.
2. I also had the car stutter at idle coming off the track in the first session on Sunday. This isn't too surprising since it was 43 degrees outside (TB + ECU had never seen these parameters yet) and the car was pulled off without the cooldown lap. I've had the stock setup stutter in this situation too, but not as bad. It never did it again.

Ultimately, only time will tell if it does either of the above again or any new hiccups popup. But with the limited testing I have so far, I'm impressed. The car feels more race car and I love it. Next event is back at COTA in early March where I should have my lightweight racing clutch and flywheel in.

I’d have to say your experience pretty well describes my impressions so far. I don’t have the aggressive added porting but wish doing an A/B comparison could be done, would be interesting. Beyond 50% Mike said it is the same so it really would be a part throttle difference but that said mine has really woken up the engine and very clearly makes more power throughout the rev range. Really great mod.

@honeybadger, did the two hiccups you Experienced throw any DTCs?

Nope. Both were over in a second or two.

My engine is very temperamental at anything but full throttle these days. Neither hiccup felt "out of the ordinary" to me, but I wanted to note them in case anyone else has the same issue.

Interested. I have an Air Flow Solutions ported intake on my car that I might like to pair with the Soler unit when available and after additional testing by the GT350 community. I already have a ported throttle body that I've been running by 1320 Junkie Performance and recently had the car remotely dialed in via RTD by Wengerd Performance. Only current "performance" mods are B line Motorsports "FF" mid pipes, 1320 Junkie Performance TB, PMAS no tune required CAI, and AFS stock ported intake. Prior to the recent work with Wengerd Tuning, the car was running very rich, but is now dialed in with great driveability, no more torque/power dip below 3.5K rpms and increased linear power across the RPM band. Wonder if the juice is worth the squeeze on going with the Soler unit, but HoneyBadger did see benefits on his engine. Thank you guys for the testing and feedback.

Did you notice if the ported intake made any difference? Also would this along with the throttle body need a tune or could both run in conjunction without voiding warranty? I know the FF pipes would need a tune but could be an interesting combo with a ported intake and throttle body and keep factory tune

Did you have the 87mm throttle body or their ported 91mm?

Now that the car is tuned, yes I definitely feel a difference. I ran all my mods without a tune and although I did feel somewhat of a difference, the car was running very rich and felt like it had more in it. I forgot to add that I had a PMAS no tine required intake as well. I did not need a tune for the mid pipes and never threw a check engine light. I used O2 extensions. The remote work definitely dialed everything in.

I have both. Been using the OEM TB all year. Last 7 sessions I've run are the 91mm TB from Soler.

TB sounds like it’s working well for some people.

Curious though, is the actual size bigger or just “effective”? I see there are partnthrottle gains to be had, but what about wide open full throttle gains? Do you think it’s picking up HP? What does the 91mm flow versus the stock 87 versus the regular GT 80?

I know a couple years ago the GT350 TB in addition to the 350 manifold was a good 1-2 punch for increasing power. I would assume that for a GT, using the larger TB would allow some gain but would also need a tune. If you have a 18+ manifold on a 15-17 then you'll have to ask your tuner if its possible.

 

[fpa1974]

I was wondering if there are any more updates from folks that are running these.

 

[SchnellGT350]

If they had more new units on the shelf I'd likely give one a try. Would rather have my stock TB sitting on the shelf for any quick runs up to the dealership for warranty work.
