No one will answer the same, or won't answer at all. Those that have shared their experiences, I've heard anywhere from 400-500WTQ max depending on the source. I'll let you know where I land with the July heat in a few weeks without the turbo upgrade but with everything on the stock turbo. I'm expecting to be 450+WTQ in the heat.
The highest torque I’ve seen is 475 torque and 544whp ultimate racing 98 octane with garret 660
Stock fuel system pretty much cars torque at 390wheel on 93. Anything more requires fuel upgrade. Hondata dyno uses dynapack. It’s more like flywheel. It’s about 10 percent higher than your typical dynojet reading. It’s closer to crank power. still that puts it around 450ish. They also did not run q16 race fuel for 18 months. That graph has only appeared recently after they developed the garret turbo kit. It’s possible not the efr turbo kit they first made. Most likely it was the e40 tune they ran most of the time. That’s around 450whp and 430 torque on dynojet. So to say they ran 480 wheel torque for 18 months I doubt it. I’m not certain it can make that much more than 475 wheel torque. Especially with how little the stock intake ports flow It’s only 160cfm. Original k20 was around 300cfm. Ported they flow 300cfm like older k20s.
Nothing major, just a worldwide pandemic.
Good points made here, I don’t see any thread hi-jacking. It’s bumping the product for PRL the P600 will be a great mod for those that are still basically stock looking for huge safe power gains over a traditional tune and PRL HVI or other variety. I will say 375WTQ via simple mods and a tune are very easily obtainable but there is a significant difference in say 375 & 425WTQ (12% increase on the 375) so this is a substantial difference as a lot of people get hung up on HP being what makes a car fast TQ is what gives you the pull. Yes HP is also a factor but TQ is every bit as relative to the “umph” factor.
This is a very good point. Torque is a lot if what makes a track car fast. My gti ran 12.45 on radials at 111 with an ots map that was rated at 338hp at the crank. It did have 402ft lbs of torque. That’s massive in the first 1/8th mile. The second half of 1/4 mile is hp. I’m one of few people that knows what a car feels lik me that makes 500ft lbs at the wheels from 2500 to 6000. It’s ridiculous. I had a 2013 zl1 previously. About 10k in mod parr’s alone. Looking at these higher powered cars like hellcat mustang gt500 and camaro zl1 the zl1 cam outrun a hellcat and hang with mustang gt500. It’s due to available torque everywhere. I’ve been in. Cars that make stupid high end power but have a tiny power band. Often you see guys get crushed by a guy with 100hp less in a car the same weight. One interesting example of too big is an mk7 golf r upgrading to a CT’s boss 500 and Due to lack of fuel and Late Spool without the fuel system it’s slower with more hp. This is where I feel the prl600 will be a really great track option. Expected to spool the earliest than any other turbo with that power capability. The only comparison might be the garret gt25-660 but using a .49 AR housing and not a .72. No one currently has tried that particular set up. The .72 housing spools after 4000. Even the g25-550 can’t spool till 3800-4000 with a .72. Prl did not change the AR but did go to a 9 blade wheel instead of 12. Having more space between the blades has a similar effect as increasing A/R.
a little birdie from PRL told me that they are hoping for the release at the end of summer.
Just as well since our cars perform significantly better in every other season!
PRL is struggling to keep up with current demands for already available parts and order demands from preorders. I had to jump through alternate hoops from an order in early June and order the same parts I ordered from a PRL dealer out of country just to keep my original build scheduled 2 months earlier and cost me hundreds of extra dollars in shipping costs alone due to no communication that the parts wouldn’t be available as promised they would be multiple times. At the time all parts were scheduled for June 28th to July 5th. Those parts since the original parts ordered slipped into August and September. I could have easily ordered the same parts from several PRL dealers in early June who had them in stock on the date of my original PRL pre-order, instead to keep in but chose to pay the extreme last minute shipping from poor communication and lack of filling my order but filling large dealer orders.
compared to stock my significant power loss now doesn’t happen till I exceed 90 degrees and unless I’m stagnant in traffic heat soaking even after driver for an hour in 90 degrees I don’t get significant power loss. The biggest difference isn’t just in intercooler but I have a bigger radiator. This significantly helps with heat soak. It’s not till I get iat over 150 from sitting in traffic do I start to get a big difference in power. Also I run a slightly leaner mixture in high rpm than ots maps. This car likes leaner mixture than typical port injection. I don’t have to worry about ruining a converter. This actually produces less overall heat. The gas temps are higher but the total heat output is lower cause there less gas. Also richer mixtures on this car seem to suffer more power loss with heat. Yes other seasons cooler temps are faster but I’d rather tune my setup in hot weather than have to revise it almost a year later. The only thing I worry about in winter is running out of fuel. Hopefully xdi will finish the high pressure pump they are working on with full race by then.
Yeah, I'm gonna be picking up a new radiator one of these days. Can't wait for more fuel pump options.
