Or well within a reasonable safety margin ? Depends on who you ask, making that kind of torque low down would give the rods a work out... But if I was making that at 4k rpm not so much.. what does your tuner say , must be a beast of a hybrid to make that so low in the rpm Quote Link to comment Share on other sites More sharing options...

My factor is I don’t push car hard at all and monitoring inlet temps I’ve never had heat soak issues. It’s a no brainer like you said for those tracking and pushing car hard but that’s not me. It’s just daily with the occasional fast take off at lights. Plus I can’t do self install so added cost of 4+hrs labour it’s not exactly “cheap” anywhere between $1700-2500 depending on IC brand etc. Quote Link to comment Share on other sites More sharing options...

meandmyself777 Posted May 26 Report Share Posted May 26 What mods do you have if you don't mind me asking just out of curiosity I did see og gassed car make 450 ftlbs torque and devil development's said it was considered safe and not much later in the rpm 3800, Quote Link to comment Share on other sites More sharing options...

Msportman Posted May 26 Report Share Posted May 26 450lbs is what Garrett quote as an upgrade with their Powermax Stage 1 turbo alongside 450bhp. Not massive amounts considering £ V BHP. My APR stage 2 was giving 415-420lbs which has now been on mine since 2017. mp2811 1 Quote Link to comment Share on other sites More sharing options...
mp2811 Posted May 26 Report Share Posted May 26 I believe that IE HO stage 2 tune on 7.5R has 450-460lbs. I think that’s a lot on stock turbo. I think the garett making 450/450 the ideal set up. Quote Link to comment Share on other sites More sharing options...

Anyone tried or tempted by the TTE - IS38 RACE Turbo to theoretically remove the potential weak point of the stock IS38 ? Quote Link to comment Share on other sites More sharing options...

Numbers don't always tell the full story, my mates Garret Stage 3 (450/460) pulls like Stage 2 on steroids. After i drove it, mine was booked in straight for Stage 3.

Did you mean Garrett Powermax stage 1? https://ecotune-scotland.co.uk/ecotune-stage-3-mqb-4wd/ Seems a nice upgrade without engine build and one that wont blow the DQ250/381 to bits! Good track package with early boost 😀 Quote Link to comment Share on other sites More sharing options...

Good track package with early boost 😀 Garret Powermax Stage 1 + HPFP = 'Stage 3' Golf R. Perfect step up from Stage 2 if you don't want to push it too far and keep it reliable. Pulls way stronger then any Stage 2 car. I chose a different Turbo as wanted to push it further but the Garrett Powermax Stage 1 + HPFP is a lovely daily setup. Below is a graph of his. mp2811 1 Quote Link to comment Share on other sites More sharing options...

Nice and comfortable on gearbox and block and well within tolerance. No lag compared to bigger turbos. Another positive is price as in reality a 450bhp Golf is a quick daily that’s affordable. You’d have to spend a lot of money on a newer quicker car or go for an older V8 Id E92 M3. / C63 and mod them so MK7/7.5 is still such a bargain Quote Link to comment Share on other sites More sharing options...

I used to own a V8 N/A Stage 2 C63 PPP (LSD from factory) and my Golf R would easily smoke it. Both the N/A C63 and M3 have legendary engines but that's about it, great sounding muscle cars but way too heavy and slow. A nice upgrade IMO, is a 2017+ Stage 2 RS3.
