Ran 17 psi all summer and not a single issue except for having to replace the TCC solenoid and wiring I the tranny.

Re: Got turbo? It's time for me
Yeah I’m pretty fortunate to have E85 all around where I live. I have 3 turbo cars (2 Hondas) and run it in all of them. It’s funny my S2000 and my Iroc are pretty much tied in a roll race with the S2K at 20psi. The Honda feels so much faster being a manual trans but amazingly the Iroc hangs right with it even though it feels so slow and boring lol.
I haven’t made very many Iroc videos this year, but there are few newer ones on my YouTube channel.
The Iroc got the snot beat out of it at Powercruise and never missed a beat. My friend Mike blew up his turbo LS swapped Dakota the day before the event so I offered for him to run home and grab the Iroc so he wasn’t bumming so much all weekend. I was feeling pretty good considering I had two cars up there and they both came home without any major issues!

I just subscribed to your channel...
Mine is getting there very slowly. I honestly can't get over how the cost went up for ebay parts, Intercoolers in particular. Years back I think I paid one hundred shipped for a FMIC with a 4" core and 3" inlet/outlet's. I wanted to get my hands on one having the inlet and outlet on the same side, with the same dimensions, and I was like whoa... maybe I'll stick with the one I already have. It's insane.

Re: Got turbo? It's time for me
It might be the brand then, because the two turbo's I went with originally years back (72mm & 76mm both.96 a/r) were about three hundred to the door. Now the turbo's themselves, same size, are close to six hundred. Same with the IC, I can find a 3" core with 2 1/2" inlet and outlet for a hundred and change, but once I come across a 4" core with 3" inlet and outlet, the price is closer to three hundred, if not more, and I remember spending a mere one hundred. I guess they have proven themselves over the years, so the demand shouldn't really surprise me. But damn lol...

Re: Got turbo? It's time for me
Theres a few 200$ and under in 4” core 3” inlet. The 300$ ones are mishimoto and those really arent that cheap of a cooler. They actually do make ok stuff it seems. Cxracing is still 198$
There are a few vendors that try to sucker a sale by way overlisting the same coolers. Theres one on there for 415 and 1217$ haha basic 200$ cxracing

Re: Got turbo? It's time for me
Yeah what’s with the random over priced stuff? I doubt they sell many but I guess if the get someone to fall for it every once in a while it’s worth it. I’ve never bought anything other than the cheapest bar/plate intercooler I could find on eBay for all three of the cars I’ve turbo’d. They seem to work well IAT-wise but I wonder if there could be much difference in restriction vs a “name brand” much more expensive intercooler. I’d be surprised if there was a significant difference but maybe. I’d assume the cores gotta be pretty similar.

Re: Got turbo? It's time for me
One thing nice is that it’s a pretty good bang for the buck combo for a gen 1 SBC . I’m ok without an LS

Re: Got turbo? It's time for me
Ha well I’m not familiar with your setup but my 17 psi isn’t really making that much power since I’m running mediocre flowing Vortec heads and a small cam. I don’t spin it past 6K and it’s probably making around 500 whp. I guess it’s still decent for an all cast stock bottom end SBC but I’m sure guys have ran higher without issue and others with carnage at lower hp levels. My engine has the newer style powdered metal rods which I’m not really sure if that’s a good thing or not.

Re: Got turbo? It's time for me
everything in my signature is what i have done to mine. Im only running 6PSI on a V3, but my IAT's are only 15-18 degress higher after a 1st, 2nd and 3rd gear street pull (and thats with the IAT before the meth nozzle) Mine did 430whp with a "super lean" 12.5 AFR, and very conservative timing table. I keep mine bellow 6100RPM to hopefully keep it alive. I looked up the PN on the rods a while back and they said they were good for "500 horsepower" per GM. Im with you, SBC ftw!
Edit - never mind now I can see your details (was on my phone before). Now I get why you made 430 at only 6 psi. Better heads and cam will do that!

Re: Got turbo? It's time for me
I can't see much about your setup. What are the details? Heads/cam/intake? What are you running for fuel? And what's your total timing under boost? Do you have any 1/4 mile times or trap speed? Do you have the powered rods or the "pink" rods?
