Fastoldguy (429) and the 472 13t record were both RACE gas dyno numbers. There are members here though with 13t's that hit 400-430 AWHP on PUMP GAS while the 13g record is 429 on RACE GAS. 20-22 psi is generally what is needed to hit 450ish AWHP with a 15g class turbo

13g's will hold 17 psi to redline max
13t's I have seen on my own car hold 24 psi to redline while laying a nice 4w burn out in its wake. Eugene held 26 psi on stock IC's with his 13t's.

I have ridden in a 13g powered car and drove one, I have 13t powered car and a 9b powered car. Honestly I wouldn't tell anyone to get 13g's when you can get 13t's for the same price. If you land on some 500 dollar turbos and you are on a budget, good BUT if you are paying the typical 700-1300 dollars for 13g's, do yourself a favor and get some 13t's for the same price as they are that much more powerful.

I don't think anyone here is saying a 13g and 13t's are equivalent because they are not. For the same relative price why wouldn't the 13t's be the better choice as they spool up great. I haven't found anyone with a set that can call them laggy or not responsive, and they make great power even at 18/19 psi which is all I want out of them. I feel they make more here than a 13g car at this boost levels because 13g's can NOT even hold this to redline (outside their efficiency range).

I was playing around with different octanes and threw in 4 gallons of e 85 which I figured brought my overall octane up to about 96ish when mixed with 16 gallons of 93 octane. Anyways I turned up my boost to 18 psi and went out tuning one morning with the wife. OH @$#%. Her comment was why is it so fast now as she graps the door handle for support? Later during the week before that tank was done I came across a yellow c6 (nonzo6) and coming back from murfreesboro I walked him fairly well. I was about 1.5-2 carlengths out going from 3rd to 4th where he quit. Those cars typically trap 116-118 and I was pulling one from a roll in my 93. So I am pretty content with these 13t's at that setting the car was on the verge of burning out anytime you went WOT in 1st meaning you better have it pointed straight or it would break them loose.

Years ago I asked Fastoldguy (13g record holder) about his Hunting Power with 13g's? Or basically the ability to pull cars from behind with 13g's (03/04 cobras and the likes of). After his response I went with 13t's since if he had to do it over again he would go with 15g's. Hindsight is always 20/20 but I learned from him and other 13g owners who say I should have gone bigger. I have 15g power with 13g spool and response (AKA 13t's). I paid 1100 already converted with less than 3k miles from another board member, Installation, who went tdo5's. Since I have had them I have been able to pull most anything I have tried though I did get worked by a modded GTO a few weeks back. Don't know what that guy had but the car was nice (black with everything blacked out) and it was loud enough to be heard over my own straight through plumbing at WOT from 4 lanes over with my windows up so who knows what it had. It was nice though I got the initial jump but at about 70 he was clearly pulling me.
